The fault code of Ma6 is P2101 without idling

This kind of problem is a typical idle motor carbon deposition serious stuck can not return to the position caused by no idling, cleaning the idle motor can solve the fault, at the same time cleaning the throttle and fuel injector effect is better, Ma six idle immediately does not have an automatic initialization function, after cleaning must use the computer to initialize, otherwise there will be a fault of idle jitter.

If there is a problem with the detection of each sensor of the engine, the computer will report the fault code to remind the owner that the engine needs to be tested and repaired, so we have to find out the reasons for this failure, and there are often the following reasons, for reference only: 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.

The specific situation is analyzed as follows; 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.

Hello, P2185: Engine coolant temperature sensor 2 is too large signal. It is advisable to check the water temperature sensor first. Thank you, hope it helps

05 Mazda 6 fault code P2009-FF:

P2009--- Variable eddy current control solenoid valve line fault. The PCM monitors the control circuit of the variable eddy current solenoid valve through the 4T terminal, and if the 4T terminal is still low voltage after the PCM turns off the variable eddy current solenoid valve, the fault code is set. Variable eddy current control solenoid valves and wiring need to be checked.

1. Open the driver's door of the Mazda. 2. Pull the Mazda's hood switch. 3. Slowly unscrew the lid of the Mazda water tank and release the high-pressure gas.

4. Lift the hood of the Mazda engine. 5. Add antifreeze to the Mazda kettle.

The reason is that the antifreeze has not been changed for a long time.

Fault **P2009 prompts the driver that the engine cooling system is missing antifreeze, and antifreeze needs to be added, generally high-quality antifreeze is replaced once a year, and those vehicles with short running time can be replaced every two years or every 30,000 kilometers, the specific operation steps are as follows:

1. Open the driver's door of the Mazda.

2. Open the hood of the Mazda and close it open.

3. Slowly unscrew the lid of the Mazda water tank and release the high-pressure gas.

4. Lift the hood of the Mazda engine.

5. Add antifreeze to the Mazda kettle.

The Mazda6 has a P0661 fault code, which means that the intake manifold tuner control circuit is low (row 1). In this case, the first thing you need to do is find the variable intake valve (on the intake manifold) with an electrical plug on it and check for voltage. If there is voltage, it is normal, and when there is no voltage, you need to check whether the circuit is connected.

It is recommended to go to the 4S shop and ask the maintenance personnel to use professional tools to troubleshoot.

In general, if the length of the Mazda6 manifold runner is optimal, the pressure wave generated by the valve closure will help direct the oil-air mixture into the engine. The problem is that the optimal intake manifold path length is different for different engine speeds. The Manifold Tuning Valve (MTV) optimizes the engine torque at different speeds by directing intake air into different lengths of intake manifold paths depending on engine speed.

This fault code appears if the electronic control unit (ECU) detects during a self-test that the intake manifold tuner control circuit voltage is below the minimum value for calibration.

The P2009 Intake Manifold Path Control Circuit Low (Row 1) Intake Manifold Path Control (IMRC) assembly is located between the intake manifold and the profile cylinder head. In order to improve engine performance, each cylinder corresponds to two intake paths, one of which is always open and the other is only open when the rev is above a certain value (say 3000rpm). The role of the IMRC actuator motor is to open and close the valve flap of the intake path according to the instructions of the electronic control unit (ECU).

Mazda6 fault **P2122

If this fault** occurs, it means that there is a problem with your throttle position sensor or accelerator pedal position sensor, and you now need to read the data stream through the decoder, and then find the throttle position sensor, as well as the accelerator pedal position sensor, and read whether these two signals change normally when you are filling the accelerator.

Can't afford to refuel. Start pressing the accelerator pedal, the speed will not go up.

The throttle was not reported as a fault.

This is the gas pedal position sensor or the throttle position sensor is broken, you now read the data stream to see which one doesn't change.

It was reported before, and later through inspection, it was found that the computer board was damaged, and the new computer version was replaced.

Is it okay after the change?

After the change, the throttle is good, and now the rest is the accelerator pedal P2122, then you test that the line on the accelerator pedal is abnormal, there are two 5 volts normally, two negative poles and two signals.
