Troubleshooting Recommendations:
- Swap Right oil pressure transducer CH B with Left oil pressure transducer CH B.
- If system checks are good, replace Right oil pressure transducer CH B and do close out.
- If fault remains, continue with next step.
- Perform wiring checks between the Right EEC and the Oil pressure transducer.
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Replace the Right EEC.
- Do close out.
