2005 GMC Envoy SLT - Page 9 - Answered Questions & Fixed issues

NO,TANK REMOVAL REQUIRED FOR CLEARANCE

check fuse then check for voltage at blower resistor. if there is voltage replace resistor. also check the wires and plug going to resistor, make sure they are not burnt or melted.

sounds like a envoy with a stuck fan clutch

wiper stalk /switch faulty replace and check fuse

Average time is about 15 hours.

This is not an OBD2 fault code it is a body related code. Engine codes start with a Letter "P"

Here is the meaning of the code.P0101 GMC Description The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).The temperature of the hot film is controlled by the ECM acertain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.

two screws one light remove then pull on light and turn over and change.

Are you saying it won't crank now, or just won't start ?There should be a solenoid that locks the shifter that is activated by the brake pedal switch. I would check for voltage at the brake switch and that solenoid.You are right in the thought about the code. It is for the throttle actuator control module and could have been set by pumping the gas pedal with the key on.

it needs to be put in the shop

Whats is tha fault code number detected there? Send us for aditional details.

You'll have to figureout if it is a fuel or ignition problem.Isthe check engine light on ?There is a long list of possible causes.Will it speed up in park ? Do you see black smoke from the exhaust ?Have you looked at the spark plugs ?

Faulty exhuast cam actuator control solenoid.

Diagnostic Test Code (DTC) P0411 is defined by SAE J2012 as "Secondary Air Injection System Incorrect Flow Detected"This DTC runs when the air injection pump and the air injection control solenoid do not have any detectible electrical faults. The PCM commands the pump to run and the solenoid to open and add forced air to the exhaust stream. The PCM then looks at the oxygen sensors in the exhaust to see if there is added oxygen in the exhaust as expected. If the oxygen sensors do not indicate that added oxygen is present, DTCP0411 sets.There is also an air pressure sensor involved in this system, but I have never replaced one of these...failure is rare.With all that said, I have replaced MANY air injection control solenoids to fix this fault. I have also replaced a couple pump motors, but not nearly as many as the solenoids.The air injection pump is located under the vehicle below the driver's seat. You should be able to hear it running occasionally - it sounds like a small vacuum cleaner when it runs. If the pump runs, this is not likely to be the problem and you will most likely have to replace the solenoid.The solenoid is located on the right side of the cylinder head. (see diagram)

using a volt meter check for current at switch, if current is present replace switch, if current is not present follow the wiring until current is found ( such as a fuse or relay) once you find current you find the problem

If it stalls in 5 seconds or less, read thru this link.http://vatspasslockpasskeysecurityhelp.yolasite.com/

Yes it was available as an option, but you can replace or install one by watching the video on it at YouTube, just click HERE

Your dealership should have seen any underlying codes. Most Cruise controls I've worked on are used on the vehicles vacuum. that is where i would start, because on a grade your engine uses more vacuum pressure thus taking from some where else.

had the same problem with a nissan truck, son had the same issue with a chevrolet p/u found in both cases it was the heater motor resister, It appears like a small circuit board, normally behind the glove compartment very easy to get to, May find the exact location from Auto Zone thats where you can purchase the board

in code reader manual a Po106 is a MAP / BARO CKT RANGE / PREFORMANCEcheck vaccume hose to your fuel injection throttle body or map sensor possible leak, plugged, also check map-sensor plugged or damaged while your there check all vaccume line save you time later.
