P0010

DTC P0010

CIRCUIT DESCRIPTION
The DTC P0010 Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit diagnostic monitors the operation of the CMP actuator system. The CMP actuator system enables the powertrain control module (PCM) to change camshaft timing when the engine is running. The CMP actuator solenoid valve controls the oil flow that applies the pressure to advance or retard the camshaft. The PCM provides a pulse width modulated (PWM) signal for control of the CMP actuator solenoid. For additional information on the operation of the CMP actuator system refer to Camshaft Actuator System Description.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC P0010 Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit

CONDITIONS FOR RUNNING THE DTC
- The ignition is ON.
- DTC P0010 runs continuously once the above condition is met.

CONDITIONS FOR SETTING THE DTC
The PCM detects an open or a short in the CMP actuator solenoid control circuit.

ACTION TAKEN WHEN THE DTC SETS
- The PCM illuminates the malfunction indicator lamp (MIL).
- The PCM stores the conditions that were present when the DTC set as Freeze Frame data.

CONDITIONS FOR CLEARING THE MIL/DTC
- The PCM turns OFF the MIL on the third consecutive trip cycle during which the diagnostic has been run and the fault condition is no longer present.
- A DTC clears after 40 consecutive warm-up cycles have occurred without a fault.
- A DTC can be cleared by using the scan tool Clear DTC Information function.

TEST DESCRIPTION

Step 1 - Step 11:

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