P1626 Saturn Code - Theft Deterrent Fuel Enable Signal Not Received

Quick Answer

The Body Control Module (BCM) produces the theft deterrent fuel enable signal when the ignition is ON and the proper key resistor pellet is sensed. Common causes include Faulty ignition switch, Ignition switch harness is open or shorted, ignition switch circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1626 Saturn Description

The Body Control Module (BCM) produces the theft deterrent fuel enable signal when the ignition is ON and the proper key resistor pellet is sensed. The Powertrain Control Module (PCM) monitors the fuel enable signal during crank. If the proper signal is present on the theft deterrent fuel enable circuit, the PCM enables fuel delivery to allow the engine to start. If the PCM detects that the fuel enables signal is not present or incorrect while the engine is running, DTC P1626 will be set. DTC P1626 can cause a no-start condition or normal operation depending on when the loss of the fuel enable signal was detected. The engine will continue to start and run if the condition that set DTC P1626 occurred after the BCM sensed the proper key resistor pellet and signaled the PCM to continue fuel delivery. The engine will start and immediately stall if the condition that set DTC P1626 occurred before the BCM sensed the proper key resistor pellet. With this condition present, the PCM will inhibit fuel delivery and the BCM will disable the starter.
