Fuel pressure regulator valve
The battery supplies power to the TCM even when the ignition switch is off. This power allows the TCM to store data such as DTC history and freeze frame data. Combined with low engine fluid pressure. The most likely reason is insufficient oil in the engine, so you should first check the fluid level. You should also ensure that the engine fluid pressure sensor is functioning.
Gas Bypass Valve
The starter relay circuit’s job is to provide a power source to the starter to crank and start the engine. Depending on the specific vehicle and its transmission configuration, several components may be involved in this process. If serial data communication is lost between any of the LIN devices on the LIN bus network, the main control module will set a no communication code against the non-communicating LIN device. The diagnostic trouble code (DTC) activates when a supervised periodic message including the transmitting device’s availability has not been received.
Synchronization Actuator
This subtype is used for internal failures of the control module that cannot be attributed to a specific subtype. Vehicle in service mode or powered on. Parking assistance is activated. Activation occurs by engaging reverse gear or operating the parking assistance switch.
Engine Oil Filter Detaring
If this error lights up and service icons appear on the dashboard, then to remove it, you need to check the operation of the electric motor of the valve lift adjustment mechanism. To reset the code, you need to determine the cause of the open loop. If serial data communication is lost between one of the LIN devices on the LIN bus network, the master control module will set a no-communication code on the LIN device that is not communicating. The Diagnostic Trouble Code (DTC) activates when a supervised periodic message including the transmitting device’s availability has not been received.
Engine Oil Filter Shutdown
The literal translation of the error is low circuit of the intake device solenoid valve located in the second bank. It is necessary to check the mechanism’s operation. Vehicle in Service Mode or ON Parking Assist is activated. Activation occurs by engaging reverse gear or operating the parking assist switch.
Engine Overspeed Limiting
If, following diagnosis, it was possible to read this code, then this combination indicates damage to the catalytic converter. It is necessary to check the device for any mechanical faults. Malfunction of the variable valve lift system. The control unit detects that the natural throttle opening position is not reached. The problem often arises after cleaning the latter. The engine stalls immediately when starting or at idle.
Engine Shutdown in Case of Overrun
When the ignition switch is turned to ON, the voltage from the ECM’s MREL terminal is applied to the EFI MAIN relay. This causes the contacts of the EFI MAIN relay to close, which supplies power to the TCM’s +B terminal. It starts at the battery, includes the ignition switch, fuses, starter solenoid, starter relay, and several safety devices, such as the clutch position sensor and neutral safety switches.
Removing restrictions from the fuel filter
Malfunction in the thermostat control system. The onboard computer reports communication issues with the control unit, so a possible cause could be a poor connection. The cooling system circuit is open, which may affect the operation of the powertrain as a whole. This indicates a malfunction in the intake airflow. The cause of the problem may be a loss of sealing or a malfunction of the mass airflow sensor. If the contaminants are not critical, you can clean the airflow meter using a special carburetor cleaner.
Fuel Filter Shutdown
The control unit indicates problems in the throttle operation. For an unknown reason, the control module was unable to provide drive in the limit position of the node. If the charging system light remains on or comes on during driving, there may be a problem with the electrical charging system. Driving while this light is on could drain the battery.
Reduction of the final cooler high temperature
The battery provides electricity to the TCM even when the ignition switch is turned off. This power supply allows the TCM to store data such as DTC history and freeze frame data. The engine started, the engine is running, and the PCM detected high voltage present at the PCM for 3 minutes after engine start. The high voltage test of the starter relay control circuit monitors the voltage signal sent by the ignition switch.
