Question about 2007 GMC Envoy

1 Answer

I have a 2007 GMC Envoy, the engine light has been on for a while now, took it to the dealer and a code P0506, they reset the light, took my $100 and said nothing is wrong, three days later, the engine light came back on, a coworker told me I need my Throttle Body cleaned, took it to another mechanic, cleaned the Throttle Body, light went out and the next day it's on again, does this mean I need to replace the Throttle Body?

Hi there, P0506 IS usally a dirty throttle body. In order to clean properly, with the battery disconnected, they need to be taken off and cleaned front and back til' they are shiny. Sticking a rag soaked with solvent in there while it's still attached isn't going to cut it, i've seen many mechanics do it this way. When they do this, they very often DO NOT unhook the battery which you NEED to do for about an hour while cleaning.. Otherwise, the computer won't relearn the clean throttle body, and you'll have your light on again. It's very easy and cheap to do it yourself. Let me know if you'd like instructions on how to do it.

I have a 04 gmc envoy xuv unknown driver message no security light will not start battery was bad got new one tryed passlock reset stills say unknown driver no start


It's a short in the instrument cluster.
I had the same problem with my 2004 XUV.
It started in early December of 2007.
Intermittent manifestations, than more persistent.
Took it to the GMC Dealer --
Of course, the Truck wouldn't do it's tricks for the Tech.
They replaced the ignition switch and sent me home.
It got progressively worse.
I waited until I was sure it would do it for the tech.
Took it back in to GMC Dealer--
It's a short in the instrument cluster.
They needed to replace the entire cluster.
I bought an extended warranty when I bought the truck.
The warranty is still in effect --
So I only had to pay the $100 deductible.
No Idea what it might cost otherwise.

Hi i have a code reading P0506 for a 06 GMC Envoy XL any recomondations


{: ) DTC P0506 Idle Speed Low
The usual cause is an excessive carbon build-up on the throttle body. If this is the case, I suggest you have your throttle body cleaned and perform an idle relearn procedure using a GM scan tool. The idle relearn or reset procedure is very important, otherwise this code may still remain even after a throttle body clean.
In a similar fashion, if the ECM/PCM (engine control module) of a high mileage vehicle is replaced and/or reprogrammed without performing the Throttle/Idle Learn procedure, the ECM/PCM may no longer compensate for existing carbon build up in the throttle body, causing it to return with a similar concern as well as DTCs P0121, P0506, and/or P0507.
There are other conditions that can also affect or reduce idle speed by increasing engine load like incorrect torque converter clutch (TCC) operation, accessories that require additional torque to operate, restricted exhaust, and mechanical conditions that limit engine speed.

Hello: Without being there when the smoke test was performed no one can say what the results of the smoke test were. I would go back to the dealer and speak to the service director/service manager and request a new gas cap.

This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck
