Seahorse Formilai fault code P1602

Reasons for the engine failure light: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

Due to engine failure, the control module has taken measures to limit the output power of the engine. This kind of fault must be found in the 4S shop with an instrument to diagnose the cause of the failure. Engine indicator refers to the indicator light used to show the working condition of the vehicle's engine.

The indicator light is used to show the working condition of the vehicle engine, when the key door is opened, the vehicle self-test, the indicator light is lit and automatically extinguished, if it is always on, it means that the engine of the vehicle has a mechanical failure and needs to be repaired.

The 7-year-old Haima Fumilai car should be the second generation of Fumilai, and he has improved the air intake system in the same comparison, but it is easy to accumulate carbon. When ensuring that the engine has no other faults, the temporary solution is to remove the positive pole of the battery for 5 minutes (the data in the CD machine should be reset when the power is off), reinstall it, it should be OK, but the temperature difference is large in the morning to start he will have a fault light on. The final solution is to go to the 4S shop to clean up the carbon deposits on the intake valve and then use the computer to eliminate the fault code.

Summary. Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, what is the actual fault of the car at present, in this case you need to detect whether the line voltage of the driving sensor to the car and the stool body is not suitable.

There is also to detect whether the power supply pin voltage of the body module and the voltage of the tie pin are appropriate, and the reputation is also to unplug and check whether the can high finger is virtual and the can low pass Weipeng signal pin voltage is exactly equal to 5 pay.

In addition, you need to check whether the wake-up signal voltage from the computer version of the engine to the starter is appropriate.

Now it is the automatic transmission gearbox to hang R gear when there is a lack of bending before refueling, and sometimes the fudou is boring and sometimes does not need to refuel to go normally. When the p block is ready, hang the other gear hand pin hall quickly, you can't hang it, and you can hang it with a tap. Thank you.

Then you just imitate this to check whether the power supply pin voltage and the voltage of the tie iron pin of the gearbox computer are suitable, and unplug the module to check whether the voltage of the CAN high CAN and low communication pins is suitable for combustion. This situation is generally caused by the unstable voltage of CAN communication.

This situation is generally a problem with the power supply of the computer version of the cargo, right, and there is a problem with the internal part of the gearbox, thank you.

If the plug of the imitation swim module is detected, the voltage of the pins of the high can and the low pass backup is exactly equal to 5, then this situation is the problem of the computer version of the gearbox.

Thank you. You're welcome, communicate with each other at any time if you have any questions.

Summary. Hello, the main pilot airbag 750, the passenger airbag 650, the airbag computer version 1200, and the seat belt 800

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

The engine failure light is on. It's a sensor and line issue. According to the wide cavity reputation you Maruyama tips should be, spark plug and caution section ignition coil problems, as well as fuel injectors, go to the repair shop with a decoder to read the fault, and then check it.

It's still powerful to drive.

Slight slippage. How to solve it?

A simple check of the transmission oil, as well as the PC version, and finally consider the interior.

If I can help you, please give me a thumbs up Thank you!

Type: Seamaster 3rd generation engine: HM479Q-A Transmission: Manual transmission.

Fault PhenomenonThe instrument failure light of the car is always on, which accelerates the feeling of meat.

The fault light of the meter is always on, indicating that the electronic control system has a fault code. The acceleration of the car is not smooth, and the oil circuit or circuit needs to be checked.

The fault code of the engine control system read by the special equipment of Haima is P2177 air-fuel ratio closed-loop control self-learning exceeding the upper limit and medium load.

Analysis and understanding of fault **P2177. Electronically controlled engine control system, in order to meet emission standards, a three-way catalytic converter is installed on the exhaust pipe. In order to obtain the best combined conversion rate of hydrocarbons, carbon monoxide and nitrogen oxides, the engine's empty-fuel ratio must be controlled at a ratio of 1.

When the engine is used for a long time, there will be wear deviations of the parts. The deposition of gum in gasoline on the nozzle, air intake, and valve, or the leakage of the intake and exhaust will cause the air-to-fuel ratio to deviate from the ratio of 1 to varying degrees, either thick or thin. These can reduce the performance of the engine.

The engine control system corrects and learns the amount of fuel injected based on deviations in the air-fuel ratio. Deviation score - small load area knows the clever domain, medium load area. When the load area reaches the upper limit set by the system and the mixture becomes thinner, the system continuously increases the amount of fuel injected until the maximum value is reached.

But in reality, the system mixture is still on the thin side, which means that the system reports a fault**P2177, alerting the car to repair. P2177 Causes: Blocked air damper, air leakage from inlet and exhaust valves, gum at the air inlet, insufficient pressure in the oil supply system.

Especially the oil pump pressure. Use the oil gauge to detect the oil pump pressure, which is lower than the normal oil pressure.

At the same time, the data stream of engine operation is read, and the fuel injection time of the faulty car is milliseconds, and the fuel injection time of the normal car is milliseconds. This situation also indicates that the electronic control system is adjusting the fuel injection time, increasing the amount of fuel injected and correcting the dilute mixture.

Replace the gasoline pump assembly and troubleshoot the test run. At the same time, the engine has plenty of power to accelerate.

The fault codes for the air-fuel ratio in the hippocampus are - P2177, P2178, P2187, P2188. The processing principle of these fault codes is the same, involving oil circuits, circuits, and machinery. In particular, the detection conditions after the processing of these fault codes are:

The water temperature of the engine is above 70 degrees, and the fault code of medium load requires 3 gears of 50 km or 5 gears of 120 km, driving 3 working cycles of sail rings. Low-load failures require idle operation for more than 3 cycles. Otherwise, after the repair, if you do not verify whether the fault has been eliminated, the car will run for a few days and then return to the shop for repair, which will increase customer complaints.
