My problam gmc model 2006 coming cde p1682 nex car not start watis solution pleas help

There are 2 ignition 1 voltage circuits supplied to the engine control module (ECM). The first ignition circuit is
provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the
internal ECM circuits associated with the throttle actuator control (TAC) operation. The second ignition 1
voltage circuit is supplied by the ignition switch through a fuse, and is used to power the remaining internal
ECM circuits. If the ECM detects a voltage difference between the 2 ignition 1 voltage circuits, DTC P1682
will set.

Get a subscription to alldatadiy.com and print out the troubleshooting steps. You've already wasted more than the cost of a good manual by replacing a good switch.

I'm pretty sure there isn't enough info here.. what's a VE SS?

Could be the steering box, but also look at the entire steering linkage for any signs of trouble.

P1116 IS FOR O2 SENSOR AND INDICATES MALFUNCTION AS WELL AS P1117.THE OTHER I NEED TO CHECK!!

The shifter cable end is probably broke.

Code p0689 may be the answer as it refers to the ECM power relay control---circuit open. code 0443 refers to the EVAP purge valve---circuit malfunction. I have not got the codes for the rest as they are specific to GMC. But I suspect that the faults will all relate to the ECM

hello sir how r u .. i have a problam on my car.GMC ENVOY . where r showing trobol code p1631.and this car is not working.. plz telll me how to solbe this problam.

Here is the definition for code 1682.
Problem could be with the ignition switch, the harness, or the computer.

Probably going to be an ignition switch problem. There is a TSB (technical service bulletin) out for this code. Run it through a dealer.

P1682 - Charging system voltage to low.
