|What are the Possible Causes of the P1682 SAAB Code?
Blown Ignition Switch Fuse
Faulty Engine Control Module (ECM)
Engine Control Module (ECM) harness is open or shorted
Engine Control Module (ECM) circuit poor electrical connection
|How to Fix the P1682 SAAB Code?
Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|What is the cost to diagnose the P1682 SAAB code?
The cost to diagnose the P1682 SAAB code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|What are P1682 SAAB code possible symptoms?
Engine Light ON (or Service Engine Soon Warning Light)
|What Does the P1682 SAAB Code Mean?
There are 2 ignition 1 voltage circuits supplied to the Engine Control Module (ECM). The first ignition 1 voltage circuit is provided by the powertrain relay, through the TAC fuse, located in the underhood fuse block. This ignition 1 voltage circuit supplies power to all the internal ECM circuits associated with the Throttle Actuator Control (TAC) operation, and to both TAC motor control circuits to the throttle body. The ignition switch provides the second ignition 1 voltage circuit to the ECM, through the ECM 1 fuse located in the underhood fuse block. This ignition 1 voltage provides power to all internal ECM circuits, except those associated with TAC operation. The ECM continuously monitors both ignition 1 voltage circuits. If the ECM detects a voltage level difference between the two circuits, Diagnostic Trouble Code (DTC) P1682 will set.
