Conditions Which Generate This Code:
The ECM is not r
eceiving a correct throttle position
signal.
System Respon
se:
The ECM will log the diagnostic code. The diagnostic
code may be vi
ewed on the electronic service tool.
The ECM returns the engine to low idle or a safe
speed when th
e problem is detected. The diagnostic
code is logged only if the engine is running. The
electronic service tool will indicate DIAG and a throttle
position of
0 percent while the diagnostic code is
active. This will happen regardless of the position of
the throttle pedal assembly. The engine will remain at
low idle or a
t the safe speed while the code is active.
Troubleshooting:
The diagnostic code is likely to be caused by one of
the following conditions:
Open circuit for the throttle position sensor
Open circu
it for the voltage supply
Perform the following diagnostic procedure: Throttle
