Throttle position sensor


the throttle position sensor will be located on the throttle body. If you follow the air induction hose that comes from the air filter housing to the engine it will be there where the hose clamps down

I am getting p0030 , p0036. po102 and p0443 on my 2007 chevy uplander ,


I think the first thing I would do is clear the codes and see how many come back after you drive it.
Code 30 and 36 are for the heater circuit in the O2 sensors on bank one. I doubt it would be both sensors, so it may be a wiring problem.
Code 102 is for a low signal from the mass air flow meter which could also be a wiring problem or the sensor or a dirty air filter.
Code 443 is for a problem with the evap purge solenoid circuit which again could be a wiring problem or the solenoid.

How do i turn up the idle on a 2007 chevy uplander


Hello,
With newer vehicles that have EFI, ( electronic fuel injection ), there are no mecanical adjustments you can make for the idle. Years ago you could just adjust the throttle cable, or, the air/gas mix.

For a bad idle, high or low, the most common causes are;

1. A dirty air filter.
2. A faulty MAF, ( mass air flow ), sensor.
These two prevent the ECM, ( electronic control module ), from determining the proper fuel/air mix ratio, which should be 1 part fuel to 14.7 parts air.

Another common cause for a bad idle is TPS, ( throttle position sensor ), sometimes the throttle body can be removed and cleaned and then reinstalled.

I hope this helps you.
Thanks, Donnie

2007 Chevy Uplander Rear Overhead A/C Vents Won't Work


Have you checked the Aux switch near the bottom of the center control console.
There should be a knob with: Aux, Off, 1, 2, 3. This is the switch for the rear AC blower.
If the driver wants to control the rear AC, use the 1, 2, 3 settings.
If you put it on Aux, Than the rear AC is controlled by the passenger in the back seat using the extra controls located on the Overhead DVD player. (The front AC must be on the rear to work)
