Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P213800

Condition
The engine control module (ECM) checks the pulse width modulation (PWM) signal and the analog signal from the accelerator pedal (AP) position sensor. The analog signal is directly connected to the Central electronic module (CEM) and the signal is transmitted via CAN communication to the Engine control module (ECM). The pulse width modulation (PWM) signal is directly connected to the engine control module (ECM).
The PWM signal is used to determine the current accelerator pedal position in a fault free system.
The Engine control module (ECM) compares both the signals to each other.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Difference between PWM signal and analog signal (via CAN) is too great.
- Incorrect value lasts longer than 16 seconds.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- The control module uses the input signal that gives the lowest accelerator pedal position.
- The control module uses the accelerator pedal position corresponding to the released position when the brake pedal is depressed at the same time.

Possible source
- Fault-trace the central electronic module (CEM).
- Contact resistance and oxidation in the terminals.
- Damaged signal cable between the Engine control module (ECM) and the accelerator position sensor.
- Short-circuit in connections.
