Overall Functional Check

Start engine and bring to normal operating temperature. Measure voltage between ground and PCM terminal No. 26 (Purple/White wire) and PCM terminal No. 27 (Pink/Black wire). Voltage reading should be 6-8 volts. If readings are not as specified, DTC should set. Go to DIAGNOSTIC PROCEDURE.
