1 | Did you perform the Instrument Cluster Diagnostic System Check? | -- | Go to Step 2 | |
2 | Start the engine. Does the engine oil pressure (EOP) gage display within the specified range? | 207-483 kPa (30-70 psi) | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 |
Does the engine oil pressure gage move up and down when commanded? | -- | Go to Step 4 | Go to Step 10 |
4 |
Does the resistance measure less than the specified value? | 5 ohms | Go to Step 6 | Go to Step 5 |
5 | Test the low reference circuit of the EOP sensor for high resistance or for an open. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 7 |
6 | Inspect for poor connections at the harness connector of the EOP sensor. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 8 |
7 | Inspect for poor connections at the harness connector of the powertrain control module (PCM). Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 9 |
8 | Replace the EOP sensor. Refer to Engine Oil Pressure Sensor and/or Switch Replacement in Engine Mechanical - 3.8L. Did you complete the replacement? | -- | Go to Step 11 | -- |
9 |
Important: Program the replacement PCM. Replace the PCM. Refer to Powertrain Control Module Replacement in Engine Controls - 3.8L. Did you complete the replacement? | -- | Go to Step 11 | -- |
10 | Replace the instrument panel cluster (IPC). Refer to Instrument Cluster Replacement . Did you complete the replacement? | -- | Go to Step 11 | -- |
11 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
