SOURCE: Gas gage doesn't work

It is possible the sender has failed, and can be replaced.

This sits in the fuel tank, so access has to be gained, usually be removing rear seats, access cover, and removing rivets and fixings.

It would be worthwhile to gain access to it and check first for any corrosion on electrical connectors. With a meter, you can check if it is working or not. If not - order a replacement before replacing it.

Please observe all safety precautions when working on fuel systems.

SOURCE: GMC Envoy w/ code P0128

Start at $89 right off the bat just for diagnostics and then depending on what they find that is causing that fault, at LEAST one hour labor, plus parts....I would say $250 is a good ballpark figure....looking up your fault code now.

My 2007 GMC envoy Denali after it has been running for a few minutes the engine dies either sitting there or while driving, the engine will turn over but will not fire. P1682 code is confirmed


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.

2004 GMC Envoy SLT 4.2L the engine will crank but want start why?


P1516 = Throttle Actuator Position Performance
P2101 = Throttle Actuator "A" Control Motor Circuit Range/Performance

Both of these codes indicate a problem with your throttle position actuator system. I'm not sure how GMC/Chevy treat this, it's possible that if the PCM/ECM will not allow the engine to start if the throttle actuator is not working properly (it may cause the engine to accelerate rapidly when running). You could try replacing the throttle actuator, but that may not solve the problem if it's a wiring issue. Best to have it checked out by a qualified mechanic.

We had a dodge dakota with the same symptoms and they found a corroded pin on the main connector to the ecm . I think P1682 is low voltage from the charging system. Hope this might help.

P0443 p0689 p1516 p1682 p2101 p2176 i have had the map sensor replaced the ignition switch, fuel pump , maf sensor throttle actuator control and the car still stalls and pulls all these codes the mechanic...


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

Po1682


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

P1682 CHEVROLET Description There are 2 ignition 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 run/crank relay 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

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


P1682 is low voltage at the ignition switch. 2 things, our ignition switches are prone to go out in Trailblazers and Envoys, so I'd look to replace this first. The only other problem would be wiring harness that leads to the ignition, check for shorts. My bet is the switch, it's not the switch the key goes into, it's under the column cover on the bottom, a little black module. Very easy to take it out and replace yourself and will run you around $35.

My 2006 Envoy intermittently wont start when key is turned. dash lights up, but no power to the starter. repeat turning the key and it will start. this problem will not happen for several days. then...


Sounds like a bad starter solonoid, you can have this tested with a volt meter when it will not start.Bad solonoids tend to work part of the time, just like the symptoms you have listed.



Please take a moment to rate my answer..............Thanks

Is there a way of turning the key a certain way to display the engine codes on my 2004 GMC Envoy


No, to display fault codes set by the ECU you will need an OBD2 scan tool. This vehicle is OBD2 compliant and that is the only way to access the fault codes.
