MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1551 - Idle Validation Switch Circuit Failure 1. Place ignition switch to OFF position and disconnect harness from throttle position sensor 690 connector (X690). a. Inspect connector 690 for dirty, corroded, bent, broken, pushed back, and extended pins. Clean and repair connector(s) as required (WP 0111 00). b. Check harness (X690) for dirt or moisture in or on connector and for missing or damaged connector seals. Remove dirt and moisture from connector. Replace missing or damaged connector seals (WP 0111 00). 2. Place ignition switch to OFF position. Disconnect throttle position sensor 690 connector (X690). a. Measure resistance between pin 1 and pin 2 on switch side of 690 connector (X690) after slowly depressing pedal until fully depressed. Resistance should be less than 125 ohms. If resistance is not as specified, replace throttle position sensor (WP 0061 00). b. Measure resistance between pin 1 and pin 3 on switch side of 690 connector (X690) with pedal released. Resistance should be less than 125 ohms. If resistance is not as specified, replace throttle position sensor (WP 0061 00). 1,2 USE TEST LEAD X690 1 OR 2 GN 3 BU BK 6 RD 5 WH 4 <125 OHMS KIT P/N 3822917 1,3 <125 OHMS
