Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.

NOTE:

It may take up to 2 min for all vehicle systems to power down before an accurate ground or low reference circuit continuity test can be performed.

Ignition/Vehicle & All vehicle systems - Off
Disconnect the electrical connector: Q6 Camshaft Position Actuator Solenoid Valve
Test for less than 10 ohms between the test points: Low Reference circuit terminal 1/A & Ground
- If 10 ohms or greater
1. Disconnect the appropriate electrical connector: K20 Engine Control Module
2. Test for less than 2 ohms between the test points: Low Reference circuit terminal 1/A@Component harness & The other end of the circuit@Control module harness
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Replace the component: K20 Engine Control Module
- Go to next step: If less than 10 ohms
Ignition - On/Vehicle - In Service Mode
Perform the scan tool control function: Camshaft Position Actuator Solenoid Valve - Off
Verify a test lamp does not turn On between the test points: Control circuit terminal 2/B & Ground
- If the test lamp turns On
1. Ignition/Vehicle - Off & Remove - Test lamp
2. Disconnect the appropriate electrical connector: K20 Engine Control Module
3. Ignition - On/Vehicle - In Service Mode
4. Test for less than 1 V between the test points: Control circuit terminal 2/B@Component harness & The other end of the circuit@Control module harness
  - If 1 V or greater - Repair the short to voltage on the circuit.
  - If less than 1 V - Replace the component: K20 Engine Control Module
- Go to next step: If the test lamp does not turn On
Remove - Test Lamp
Perform the scan tool control function: Camshaft Position Actuator Solenoid Valve - On
Verify the scan tool parameter: Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status = Not Run or OK
- If not the specified state
1. Ignition/Vehicle - Off
2. Disconnect the appropriate electrical connector: K20 Engine Control Module
3. Test for infinite resistance between the test points: Control circuit terminal 2/B@Component harness & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance - Replace the component: K20 Engine Control Module
- Go to next step: If the specified state
Connect a 3 A fused jumper wire between the test points: Control circuit terminal 2/B & Ground
Perform the scan tool control function: Camshaft Position Actuator Solenoid Valve - On
Verify the scan tool parameter: Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status = Malfunction
- If not the specified state
1. Ignition/Vehicle - Off & Remove - Jumper wire(s)
2. Disconnect the appropriate electrical connector: K20 Engine Control Module
3. Test for less than 2 ohms between the test points: Control circuit terminal 2/B@Component harness & The other end of the circuit@Control module harness
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Replace the component: K20 Engine Control Module
- Go to next step: If the specified state
Verify DTC P0011 is not set.
- If the DTC is set
1. Ignition/Vehicle - Off
2. Remove the component: Q6 Camshaft Position Actuator Solenoid Valve
3. Inspect the following components:
  - Camshaft Position Actuator Magnet - Refer to: Camshaft Position Actuator Magnet Cleaning and Inspection
  - Camshaft Position Actuator Solenoid Valve - Refer to: Camshaft Position Actuator Solenoid Valve Inspection
  - Camshaft Position Actuator - Refer to: Camshaft Position Actuator Cleaning and Inspection
  - If a condition exists - Repair or replace as necessary
- Go to next step: If the DTC is not set
Test or replace the component: Q6 Camshaft Position Actuator Solenoid Valve
