P0690 is stored, it means that the powertrain control module (PCM), has detected an abnormality in the relay which supplies it with voltage. This particular code will be stored if power relay sensor circuit voltage exceeds the maximum allowable parameter. The PCM power relay is used to apply battery voltage safely to the appropriate PCM circuits. It is a contact type relay that is activated with a signal wire from the ignition switch. This type of relay typically uses a five-wire design. Constant battery voltage is applied on one wire; ground on another. A third circuit carries a signal from the ignition switch and a fourth supplies voltage to the PCM. The fifth wire is the power relay sense circuit. It is used by the PCM to monitor power relay voltage. If the PCM detects a high voltage condition on the power relay sense circuit, a code P0690 will be stored and a malfunction indicator lamp (MIL) may be illuminated.
