Circuit/System Verification

Ignition ON, observe the scan tool Engine Oil Pressure Switch parameter with the ignition switch turned ON and the engine not running the reading

should be Low, with the engine running the reading should be OK.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the B37 Engine Oil Pressure Switch.

2. If applicable, test for less than 30 ohm between the low reference circuit terminal B and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20

Engine Control Module.

3. Ignition ON, verify the scan tool Engine Oil Pressure Switch parameter is OK.

瀚慖f not the specified value, test for the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the K20 Engine

Control Module.

4. Install a 3 A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool Engine Oil Pressure Switch parameter

is Low.

瀚慖f not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the

K20 Engine Control Module.

5. If all circuits test normal, test or replace the B37 Engine Oil Pressure Switch.

Component Testing

Static Test

1. Ignition OFF, disconnect the harness connector at the B37 Engine Oil Pressure Switch.

2. Test for infinite resistance between the signal terminal A and the low reference terminal B with the switch in the open position.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the engine oil pressure (EOP) sensor.

2. Ignition OFF, test for less than 1.0 ohm between the low reference circuit terminal C and ground.

瀚慖f greater than the specified range, test the circuit for an open/high resistance. If the circuit tests normal, replace the ECM.

3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal B and ground.

瀚慖f less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal,

replace the ECM.

瀚慖f greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.

4. Verify the scan tool Engine Oil Pressure Sensor parameter is less than 0.2 volt.

瀚慖f greater than the specified range, test the signal circuit terminal A for a short to voltage. If the circuit tests normal, replace the ECM.

5. Install a 3A fused jumper wire between the signal circuit terminal A and the 5-volt reference circuit terminal B. Verify the scan tool Engine

Oil Pressure Sensor parameter is greater than 4.8 volts.

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the ECM.

6. If all circuits test normal, test or replace the EOP sensor.
