Fault codes
PID 91, Code 2.2.1 Accelerator pedal sensor
Reason:
Faulty sensor, connector or cable.
Reaction:
The engine goes into “limp home” mode.
Action:
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.
WARNING!
Read through the safety advice for care and maintenance work in the “Safety information”
chapter before starting work.
Code 2.0.0
No faul
ts
There are no active faults.
PID 190, Code 2.1.1 Engine speed sensor,
camshaft
Reason:
Faulty sensor, connector, cables or incor-
rect distance to cam wheel. High frequency interfer-
ence.
Reaction:
Engine is shut off.
Action:
• Check that the engine speed sensor is installed
with the correct distance to the camshaft.
• Check the cables for the engine speed sensor for
breaks and short circuits.
• Check the connector for poor contact.
• Check engine speed sensor function. Change the
sensor as necessary.
PID 190, Code 2.1.4 Overspeed
Reason:
The engine speed is or has been higher
than the permissible limit.
Reaction:
Fuel injection ceases and the fault code
lamp lights up until the engine speed falls below the
permissible limit again.
Action:
• Check the control rod for the injection pumps.
• Check the actuator, replace it if necessary.
• Check the cables for the actuator for breaks and
short circuits.
• Check the number of teeth on the camshaft
wheel.
• For VE engines, it may be necessary to check the
function of the “limp home” mode
