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 appropriate electrical connector: B23 Camshaft Position Sensor
Test for less than 10 Ω between the test points: Low Reference circuit terminal 2 & Ground
- If 10 Ω or greater
1. Disconnect the appropriate electrical connector: K20 Engine Control Module
2. Test for less than 2 Ω between the test points: Low Reference circuit terminal 2 @ Component harness & The other end of the circuit @Control module harness
  - If 2 Ω or greater - Repair the open/high resistance in the circuit.
  - If less than 2 Ω - Replace the component:K20 Engine Control Module
- Go to next step: If less than 10 Ω
Ignition - On / Vehicle - In Service Mode
Test for 4.8 to 5.2 V between the test points: 5 V Reference circuit terminal 1 & Ground
- If less than 4.8 V
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector:K20 Engine Control Module
3. Test for infinite resistance between the test points: 5 V Reference circuit terminal 1 @ Component harness & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance
4. Test for less than 2 Ω between the test points: 5 V Reference circuit terminal 1 @ Component harness & The other end of the circuit @ Control module harness
  - If 2 Ω or greater - Repair the open/high resistance in the circuit.
  - If less than 2 Ω - Replace the component:K20 Engine Control Module
- If greater than 5.2 V
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector:K20 Engine Control Module
3. Ignition - On / Vehicle - In Service Mode
4. Test for less than 1 V between the test points:5 V Reference circuit terminal 1 @ Component harness & Ground
  - 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 between 4.8 and 5.2 V
Test for 4.8 and 5.2 V between the test points: Signal circuit terminal 3 & Ground
- If less than 4.8 V
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector:K20 Engine Control Module
3. Test for infinite resistance between the test points: Signal circuit terminal 3 @ Component harness & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance
4. Test for less than 2 Ω between the test points: Signal circuit terminal 3 @ Component harness & The other end of the circuit @ Control module harness
  - If 2 Ω or greater - Repair the open/high resistance in the circuit.
  - If less than 2 Ω - Replace the component:K20 Engine Control Module
- If greater than 5.2 V
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector:K20 Engine Control Module
3. Ignition - On / Vehicle - In Service Mode
4. Test for less than 1 V between the test points:Signal circuit terminal 3 @ Component harness & Ground
  - 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 between 4.8 and 5.2 V
Verify DTC P0341, P0366 is not set.
- If the DTC is set
  Verify the following conditions do not exist:
- B23 Camshaft Position Sensor & Reluctor Ring - Excessive play/Foreign material passing between the components/Incorrect air gap /Incorrect installation/Loose/Visible Damage
- Engine Oil - Contaminated/Dirty
- Timing Chain or Timing Belt - Visible Damage /Worn
- Timing Chain Tensioner or Timing Belt Tensioner - Visible Damage /Worn
  - If a condition exists - Repair or replace as necessary
  - If no condition exists - Test or replace the component:B23 Camshaft Position Sensor
- Go to next step: If the DTC is not set
Test or replace the component:B23 Camshaft Position Sensor
