DTC P0524: OIL PRESSURE TOO LOW

1. Ensure engine oil level is correct. Oil pressure should be checked. Disconnect engine oil pressure sensor connector. Engine oil pressure sensor is located on driver's side of cylinder block, just behind Engine Control Module (ECM) and contains 3-pin connector. See Fig. 48 . ECM is located on driver's side of engine, just in front of fuel transfer pump and contains a 50-pin connector. Remove engine oil pressure sensor and install mechanical oil pressure gauge.

2. Start engine and allow engine to warm to normal operating temperature. Check oil pressure with engine idling and at 2000 RPM at normal operating temperature. Oil pressure should be at least 10 psi (.7kg/cm2 ) at idle and at least 30 psi (2.1 kg/cm2 ) at 2000 RPM. If oil pressure is within specification, replace engine oil pressure sensor. Install and tighten engine oil pressure sensor to 12 ft. lbs. (16 N.m). Perform TEST VER-2A . If oil pressure is not within specification, repair engine mechanical problem as necessary. Install and tighten engine oil pressure sensor to 12 ft. lbs. (16 N.m). Perform TEST VER-2A .
