DN6 INTERMITTENT CHECK
• Ignition OFF.
• PCM connector connected.
• IAT2 Sensor connector connected.
• MAP/CACT Sensor connector connected.
• MAP/IAT2 Sensor connector connected.
• TCBP/CACT Sensor connector connected.
• Ignition ON, engine OFF.
• For the MAP/CACT or TCBP/CACT sensor,
• Access the PCM and monitor the CAC_V (VOLT) PID.
• For the IAT2 or MAP/IAT2 sensor,
• Access the PCM and monitor the IAT2 (VOLT) PID.
• Lightly tap on the sensor in question and wiggle the harness connector to simulate road shock.
Is there a large change in the voltage reading?
Yes | No |
|---|---|
REPAIR as necessary. If no concerns are present, INSTALL a new sensor in question. REFER to the Workshop Manual Section 303-14, Electronic Engine Controls. Clear the PCM DTCs. REPEAT the self-test. | GO to DN7 . |
DN7 SIMULATE THE OPPOSITE SIGNAL TO THE PCM
• Ignition OFF.
• IAT2 Sensor connector disconnected.
• MAP/CACT Sensor connector disconnected.
• MAP/IAT2 Sensor connector disconnected.
• TCBP/CACT Sensor connector disconnected.
• Ignition ON, engine OFF.
• For the MAP/CACT or TCBP/CACT sensor,
• Access the PCM and monitor the CAC_V (VOLT) PID.
• For the IAT2 or MAP/IAT2 sensor,
• Access the PCM and monitor the IAT2 (VOLT) PID.
Is the voltage greater than 4.2 V?
Yes | No |
|---|---|
For DTCs P007B, P0096 or P00CE, GO to DN8 . For all others, UNABLE to duplicate or identify the concern at this time. GO to Pinpoint Test Z . | GO to DN10 . |
