Engine Control System - 1.8L (Lnk) - DTC P0010-P0128: Overview Pontiac Vibe I рестайлинг

Test Description

The numbers below refer to the step numbers in the diagnostic table.

1. 1: The Diagnostic System Check - Vehicle prompts the technician to complete some basic checks and store the Freeze Frame data on the scan tool, if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later reference.
2. 4: This step checks the operation of the CMP actuator solenoid valve. This inspection is to be performed when the vehicle is idling at normal operating temperature. Turning ON the CMP actuator solenoid at idle will advance the camshaft enough to cause a significant drop in engine speed.
3. 8: This step checks for electrical resistance in the wiring and connections of the CMP actuator solenoid circuit. Circuit resistance as small as 25 ohms can cause a DTC P0010 to set.

Description

The DTC P0016 Crankshaft Position (CKP) - Camshaft Position (CMP) Correlation diagnostic monitors the relationship between the CKP sensor and CMP sensor. The powertrain control module (PCM) is continuously comparing the CKP sensor signal to the CMP sensor signal. The PCM can detect incorrect camshaft to crankshaft timing and analyze CMP actuator system operation with the DTC P0016 diagnostic.

The DTCs MUST be cleared in order to view the Current Status of the system diagnostics being performed. Do not forget that I/M System Information tests only indicate that the test has run, not whether the test passed or failed. The Last Test Failed screen must be checked for related DTCs in order to determine the outcome of the diagnostic test involved.
