Monitor GDS Data
- Connect GDS to DLC (Data Link Cable).
- Warm up the engine to normal operating temperature.
- Monitor "Low Pressure Fuel Pressure" parameter on the "Current Data" with GDS.
- Are the parameters displayed correctly?
YES
- This can be an intermittent fault caused by poor contact of the sensor's and/or ECM (PCM)'s connector. Or, ECM (PCM) memory was not cleared after repair. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace the relevant component (s) as necessary, and go to "Verification of Vehicle Repair ".
NO
- Go to "Terminal and Connector inspection ".
