2004 GMC Envoy XUV - Answered Questions & Fixed issues

It is part of the throttle body. If you want to replace the throttle position sensors. You will have to replace the throttle body as a unit....Note: There should be two of them in your scan tool data screen.

Latch actuator is probably bad an needs replacing . Your best bet , take it to a qualified repair shop. An have it checked .

Hello Anonymous, These system are controlled by an electronic module that should send a fault code to the BCM (Body Control Module) and accessed via the DLC (Diagnostic/Data Link Connector) if a fault is present. Some Auto parts stores will connect a OBDII scanner to your vehicle for free and provide you with a starting point should any fault codes be present. Fault code scanning is always the first step in trouble shooting a problem.

4.2 engine? It takes a bit to get it off. Why do you want to get to them? I can say these aren't your problem. And if they are, you have other problems that replacing them is only a short term fix.

Check to see if you have brake lights. If the brake light switch under the dash is broken or mis-aligned it can cause the shift lock to stay on

check the fuse/relay. if it is neither of these check the switch with a multimeter. If you can hear the motor trying to move the glass when you try the switch it may be the regulator needs attention. It may be the motor needs to be replaced. check fuse and relay along with the switch first then the regulator and motor afterwards. Replacing the small electronics is obviously easier than having to open up the tailgate to check the mechanics of the winedow.

hi there the blower has a fuse first check the fuse can find the fuse location in the owners manual if its not the fuse then some unit inside the blower went bad

The tailgate assembly requires regular lubrication and adjustment in order to keep functioning properly. If it has stopped functioning, follow the manufacturer's recommendations for periodic lubrication and adjustment.

Good place to get a vacuum gauge hooked up and identify problems using that tool. Without the gauge, check your exhaust and see how much if passing through the converter. You can do this by testing the temperature of the exhaust before and after the converter making sure the converter/exhaust isn't restricted. As the vehicle warms up a bad converter can cause the symptoms you are describing.

P1860 = TCC PWM Solenoid Circuit Electrical P0740 = Torque Converter Clutch Circuit/Open and P0785 = Shift Timing Solenoid "A" Maybe spurious codes, I can't tell.

The C0292 code in your 2004 GMC Yukon Denali XL indicates a communication issue between the Powertrain Control Module (PCM) and the Electronic Brake Control Module (EBCM). Here are some steps to diagnose and potentially fix the problem: Check Ground Connections: Inspect the ground connections related to the PCM and EBCM. Follow the ECM ground and ABS module ground. Check the ground on the firewall (driver's side) and the frame rail under the driver's seat. Also, verify the engine ground on the driver's side. Inspect Wiring and Connectors: Visually examine the wiring harness and connectors associated with the EBCM. Look for any signs of damage, such as broken wires or corroded pins. Ensure that the connector pins are not bent or pushed out. Pay attention to any loose or poor electrical connections. Consider the Tune: If you've recently modified the vehicle's tuning, consider reverting to a different tune. Sometimes, a specific tune can cause communication issues. If you suspect the tune, contact the tuner for further guidance1. Professional Diagnosis: If the above steps don't resolve the issue, it's advisable to seek professional help. A qualified mechanic can perform a thorough diagnosis using specialized tools. Keep in mind that diagnostic costs typically range from $75 to $150 per hour.

It is not legal to 'adjust' speedometers. Fit the correct sized rims and tyres and the speedometer reading will be correct or use a satnav for real time speed.

The BCM is located on the lower left side of the dashboard just below the steering column

Fuel injectors are typically driven directly by power transistors in the engine computer. Relays are just not fast enough to provide the fine timing control needed. There might be an individual fuse for each injector soldered to the computer board, but I haven't ever looked at one for your model, and I've never seen injectors individually fused. Before chasing that, verify that the electrical resistance of the injector coil is the same as the other injectors. The typical resistance is between 100 and 1000 Ohms. If the coil resistance differs by more than 10%, replace the injector coil (it may be easier to remove the coil from a new injector and switch it with the old one than to pull the entire injector out and replace it, if not, change the injector). Shorts in the coil that lower the resistance are sometimes a problem. Also check the injector cable for continuity. An easy way is with an ohmmeter that can read at least 20 Megohms. First, check the resistance between the terminals on a good cable. You should read a very high resistance - this is the leakage through the transistor and any protective components, and is some number between 5 and 20 megohms. The exact number doesn't matter, as long as you see something and it is not a short circuit (less than 1 Ohm). This verifies that the test will work (if it reads over-range, either your probe tips can't reach the contacts in the connector, or the test is otherwise not valid). Next, repeat on injector 1. If it reads open circuit (over-range), check the injector cable (note: an open fuse will give the same result as a broken wire).
