Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
NOTE: Verify proper engine oil level before continuing with diagnosis.
  1. Ignition OFF, disconnect the harness connector at the B35C engine oil level sensor.
  2. Ignition OFF for 90 s, test for less than 2 Ω between the ground circuit terminal C and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Engine Oil Level Warning parameter reads Low.
    • If the Oil Level Warning parameter reads OK, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the ECM.
    4. NOTE: If a short to voltage is found on the signal circuit, the fuse in the 3 A jumper wire will open.
  4. Ignition ON, install a 3 A fused jumper wire between the signal circuit terminal A and the ground circuit terminal C. Verify the scan tool Engine Oil Level Warning parameter reads OK.
    • If the Engine Oil Level parameter reads Low, test the signal circuit terminal A for an open/high resistance. If the circuit tests normal, replace the K20 ECM.
  5. If all circuits test normal, test or replace the B35C engine oil level temperature sensor.
