Circuit Description
This DTC indicates that there is an intermittent problem with the relationship between CKP Sensor A and CKP Sensor B.
Conditions for Running the DTC
Engine cranking or running.
Conditions for Setting the DTC
The PCM detects an intermittent loss of match between the two CKP sensor signals.
Action Taken When the DTC Sets
| • | The PCM illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails. |
| • | The PCM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the PCM stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the PCM records the operating conditions at the time of the failure. The PCM writes the conditions to the Freeze Frame and updates the Failure Records. |
Conditions for Clearing the MIL/DTC
| • | The PCM turns the MIL Off after three consecutive drive trips that the diagnostic runs and does not fail. |
| • | A last test failed (current DTC) clears when the diagnostic runs and does not fail. |
| • | A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures. |
| • | Use a scan tool in order to clear the MIL/DTC. |
| • | Interrupting the PCM battery voltage may or may not clear DTCs. This practice is not recommended. Refer to Powertrain Control Module (PCM) Description , Clearing Diagnostic Trouble Codes. |
Diagnostic Aids
Notice: Use the connector test adapter kit J 35616-A for any test that
requires probing the following items:
• The PCM harness connectors • The electrical center fuse/relay cavities • The component terminals • The component harness connector
If the problem is intermittent, refer to Intermittent Conditions .
Test Description
Number(s) below refer to the step number(s) on the diagnostic table.
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Powertrain On-Board Diagnostic (OBD) System Check? | -- | ||
2 | Is DTC P0335 or P0385 also set? | -- | Go to the applicable DTC | |
Does CKP Sensor Status indicate Time A? | -- | |||
4 | Does CKP Sensor Status indicate Time B? | -- | ||
5 | Move the related harnesses and connectors (by hand only) while monitoring the scan tool display. Does CKP Sensor Status change to Time A? | -- | ||
6 | Did CKP Sensor Status change to Time B? | -- | Refer to Diagnostic Aids. |
