Brief Description of DTC
Loss of a 5 volt feed to the Throttle Position Sensor has
been detected.
APPS supply voltage input below the minimum
acceptable voltage.
Loss of a 5 volt feed to the MAP Sensor has been
No difference is recognized between the MAP reading at
engine idle and the stored barometric pressure reading.
A prolonged lean condition is detected during Wide Open
MAP Sensor signal does not correlate to Throttle Position
Sensor signal. Possible vacuum leak.
An open or shorted condition detected in the ASD or CNG
shutoff relay control ckt.
An open or shorted condition detected in the auto
shutdown relay circuit.
No Z1 or Z2 voltage sensed when the auto shutdown
relay is energized.
An open condition detected In the ASD relay output
Relationship between Cam and Crank signals not correct
Loss of the Cam Position Sensor or Crank Position
sensor has occurred. For PL 2.0L
PCM is unable to learn the Crank Sensor's signal in
preparation for Misfire Diagnostics. Probable defective
Crank Sensor
An open or shorted condition detected in the Wait to Start
Lamp circuit.
Loss of 5v feed to the EGR position sensor.
Sensor supply voltage for ECM sensors is too high.
Insufficient flow of secondary air injection detected during
aspirator test (was P0411)
Excessive flow of secondary air injection detected during
aspirator test (was P0411).
Internal temperature sensor input voltage out of an
acceptable range.
An open or shorted condition detected in the transmission
fan relay circuit.
An open or shorted condition detected in the PCV
solenoid circuit.
EATX RPM pulse generator signal for misfire detection
does not correlate with expected value.
