MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1187 - Sensor Voltage Supply Failure - Continued 6. Place ignition switch to OFF position. Disconnect sensor harness and actuator harness from engine ECU. a. Measure resistance from sensor harness connector pins 18, 25, and 45 to engine block ground. Resistance should be greater than 100k ohms. If engine harness requires replacement, notify SRA. b. Measure resistance from actuator harness connector pins 19 and 29 to engine block ground. Resistance should be greater than 100k ohms. If engine harness requires replacement, notify SRA. 7. Place ignition switch to OFF position. Disconnect sensor harness and actuator harness from engine ECU. Disconnect oil pressure/temperature sensor and coolant level sensor jumpers. USE TEST LEAD KIT P/N 3822758 SENSOR HARNESS: PINS 18,25,45 TO ENGINE BLOCK GROUND ACTUATOR HARNESS: PINS 19 AND 29 TO ENGINE BLOCK GROUND >100K OHMS >100K OHMS
