What Does P0626 Mean? This code indicates that a fault has been detected in the generator field control circuit. The PCM or one of the other supporting control modules has detected this fault. These control modules may include (but are not limited to) the alternative fuel control module, the body control module, the antilock brake control module, the instrument panel control module, the fuel injection control module, the turbo control module, the anti-theft module, the cruise control module, the traction control module, proximity alert module, and the climate control module. engine code P0626P0626 fixobd P0626dtc P0626obd code P0626obd2 P0626P0626 car codediagnostic code P0626car code P0626check engine code P0626fehlercode P0626P0626 fiatcodigo P0626codigo falla P0626P0626 kody b??dówcodigo de falla P0626 What are the common causes of P0626 ? The fault detected on the generator field code may have several causes: Faulty alternator Bad battery Damage or corrosion on generator control module circuit Bad wiring somewhere in the vehicle Poor communication between generator control module and powertrain control module How do you troubleshoot P0626 ? You might continue by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data. With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
