We have a 08 Acadia as well that has given up a few problems and its service air bag light just came on, again. With my dashboard saying reduce power. It'll drive fine alternating between higher and lower speeds the whole way. The engine is at idle with no input from the accelerator pedal. The voltage should not change more than 1 volt. Did relearn procedure twice to no avail.
You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. Each reference bus provided 5-volt reference circuit for more than one sensor. Happened once, I reset it and didn't come back for a few months. Couple days ago it showed up, I reset the code and it came back almost immediately. Enter the 5 character trouble codes in the search box and submit the search. Unfortunately its out of warranty. The control module monitors the voltage on the 5-volt reference buses.
My wire was a 4x2 and the nnbs throttle is a 3x2. Instead, spray the cleaner on a soft cloth and wipe the parts. Bulletin says to start with fuel tank pressure sensor. If you do not feel qualified to do this, take it to a reputable mechanic to troubleshoot and correct it for you. The above condition is present for 1 second.
Go to Step 2 1. First I disconnected the battery, I then removed the throttle body and replaced the air filter. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. I tried every trick under the sun to get it to reset. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
Thanks 2 years ago 2003 silverado 5. Dealer says it is probably only one sensor that is causing all the other codes. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. But couldn't use the 4 bolt throttle body.
Did you find and correct the condition? I put a v8 in a while ago. Diagnostic Aids It may be possible to locate the fault by disconnecting one component at a time from the 5-volt reference circuit while viewing the 5-Volt Reference circuit parameter on the scan tool. The engine was started without the pause for two minutes?????? Performed the idle speed relearn several times as described in this video. To perform the test, the computer pulls a vacuum and checks to see if the vacuum holds. I think I just answered my question.
I again disconnected the battery terminal. Connect the negative battery cable. Refer to Circuit Testing in Wiring Systems. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. I am not frustrated with the dealership, just frustrated with the situation. Did not solve high idle issue.
The control module monitors the voltage on the 5-volt reference buses. For technical bulletins regarding steering click here: cardone. The reset sequence initially did not work. I drove about 60 miles using various backroads to vary speed. Mine was so bad that I actually prematurely wore out my brake pads! In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. That method dumps extra oxygen into the converter to react with the extra fuel and burn it off. Your gas mileage will also be terrible, so you should try and fix it as soon as you can.
