What is the problem with the fault code P0106 after the overhaul of Chang an Star

The function of the Manifold Absolute Pressure (MAP) sensor is to measure the pressure (vacuum) inside the intake manifold. The Powertrain Control Module (PCM) then uses the difference between the intake manifold pressure and the atmospheric pressure, which is linearly related to the engine load, as a basis for determining the basic injector injection to help the engine achieve the optimal air/fuel ratio at different loads. The role of an atmospheric pressure sensor (sometimes referred to as a high altitude compensator, HAC) is to transmit the atmospheric pressure to an electronic control module in the form of an electrical signal.

Atmospheric pressure changes with weather and altitude. The lower the pressure, the thinner the air. The Powertrain Control Module (PCM) corrects the fuel supply based on the value of atmospheric pressure to help the engine achieve the optimal air/fuel ratio.

This fault code appears if the electronic control unit (ECU) detects that the manifold absolute pressure (MAP) sensor signal voltage of the barometric pressure sensor is outside the normal range of calibration. Causes of failure include failure of the MAP sensor circuit, connector, or sensor itself; Barometric pressure (BARO) sensor circuitry, connectors, or the sensor itself malfunctioning; or electronic control module (PCM or ECM) failure, etc.

Changan Star Card P0496 fault code solution.

Hello dear, I am inquiring for you, I will reply to you immediately, please wait!

Hello, I'm glad to answer for you: The solution to the P0496 fault code is mainly to check whether the fuel tank cover is broken or not closed tightly, if so, it should be repaired or replaced. The cause of the failure is as follows:

1. The fuel tank cover is damaged or not closed tightly. 2. There are leaks in the pipeline of the EVAP system, such as renting and touring. 3. The carbon canister control solenoid valve and its circuit are faulty.

4. The ventilation solenoid valve and its wiring are faulty. 5. The fuel tank pressure sensor and its circuit are faulty. Here are some other things to look at:

1. The position of the carbon canister control system conversion valve on the car: the carbon canister control system conversion valve is generally installed between the carbon canister and the intake manifold. 2. The function of the transfer valve of the carbon canister control system:

The gasoline vapor in the carbon canister is brought into the cylinder by clean air under the action of the vacuum degree of the intake pipe to participate in combustion. Hope the above can be helpful to you.

Chang'an Star 16V, P0123 fault meaning is throttle throttle pedal position sensor switch A circuit is high, that is, the difference between the electronic throttle and throttle opening information value is too large, that is, the throttle is too dirty, cleaning can be solved, the specific operation steps are as follows:

1. Loosen the throttle connecting hose.

2. Disconnect the hose.

3. Use carburetor cleaner to spray the throttle.

4. Use a brush to clean the throttle.

5. Install the intake hose back to solve the problem.

This fault is generally a problem with the circuit and oil circuit, which needs to be solved by elimination.

Check the carbon canister and solenoid valve.

2.The computer retrieves the fault code, and checks the engine control unit, engine data stream, fuel adjustment value, and oxygen sensor value. Data from major sensors such as the intake manifold absolute pressure sensor and the throttle position sensor (TPS).

Check the exhaust manifold and three-way catalytic converter. The engine is high-voltage and the spark plug is normal, which can basically rule out the possibility of failure of the ignition system. If the air intake, exhaust, and ignition are normal, you can check the crankshaft pulley again.

It is estimated that there is a high possibility of oil circuit problems, and the oil pressure, pressure holding state, and fuel injection pulse width of the fuel system are tested. It's really not good, oil change pump assembly, carbon canister.

3.Nozzle cleaning, throttle body cleaning.

4.Idle motor, generally 4S has the equipment to detect the idle motor, generally the motor starts no problem if the vibration will be very slight, when the oil or loose oil is given, it will shrink up and down and reflect more quickly.

<> Extended Information: Fault **P0501 is described in detail as follows: System Scope of Failure:

Applicable vehicle speed and idle speed control: All car manufacturers. Chinese Meaning Explained:

The vehicle speed sensor can malfunction. English meaning: There is currently no knowledge about P0501 fault code:

1。Installation position and function of the vehicle speed sensor: The vehicle speed sensor is installed on the housing near the transmission output shaft to detect the driving speed of the vehicle.

2.The type, structural principle and influence of vehicle speed sensor. Vehicle speed sensors are analog AC signal generators that generate AC voltage signals.

The amplitude of the output signal is proportional to the rotational speed of the magnetic wheel. The vehicle speed sensor is a three-wire system, including a power cable, a signal cable, and a ground wire. Antecedents and consequences:

1。Fault ** Explanation: The vehicle speed sensor detects the speed of the electronically controlled vehicle, and the control computer uses this input signal to control the engine idling, locking the torque converter of the automatic transmission, shifting the automatic transmission, switching the engine cooling fan, cruising and other functions.

But my car doesn't have an ABS sensor and it starts.

And I also changed the engine crankshaft position sensor.

Will there be a problem with the signal teeth of the flywheel?

Hello, your car without ABS is a problem with the flywheel disc signal teeth.

The car is on normal ground.

Because the above things are new, it proves that two things are not available in ABS, and it is possible that the problem of the flywheel wash signal also exists.

If you don't have ABS to drive normally, won't you have any abnormal noise when driving?

I don't feel it. <>

The answer is a small suggestion for you, don't step on the brakes if you don't have ABS. Because if you step on it, it will cause the direction to lose control.

Got it, thank you.

The main ABS system is connected to the wheelset sensor, so it is possible that such a problem exists. <>
