SOURCE: Check Engine Light with Code P0072 on 2004 Volvo XC90

Grounding issue "Circuit low" = ground wire problem or another system on the same circuit using too much current.

Check all wiring issues and then correct the issue to have the code go away :)

SOURCE: Engine miss when ambient air temp increases not water/engine temp

there is an ambient temp. sensor in the intake air ducting, if its a small round two wire plug you can unplug it and the computer will think its -40C. You will set a code when you do this, but should go away after you plug it back in.
Depending on the engine you could have a cracked mainshaft in your distributor which is quite common, unfortunately most cracks are on the underside of the shaft which requires removing the distributor.

Where is the cabin air temp sensor located on a 2005 avalanche 1500 base 5.3l

On some trucks it is mounted in the headliner above the driver's head. Looks like a round grille. Need to lower headliner to replace it, if that's where it is.

Air conditioner will not come on. The tempeture gage is reading -40. The sensor is not reading properly.

Hi ruswashingto,

The air conditioner may not work properly if your ambient temp is reading -40. The a/c control unit monitors ambient temp so that it does not operate at too low outside temps. I would recommend fixing the ambient temp sensor and rechecking your a/c operation.

Humming sound coming from the small speaker over my head ?

That "speaker looking thing" above the drivers head on the headliner is a part of the climate control system.

Here is the GM bulletin regarding it if you are running in to these issue:

Document ID# 1639237

Subject: Buzz Noise From Headliner Above Driver - keywords ac air aspirator cover fan grille HVAC interior microphone sensor speaker temperature vent vibration #PIT3511 - (03/29/2005)



Models: 2000-05 Cadillac Escalade

2002-05 Chevrolet Avalanche

2000-05 Chevrolet Silverado, Suburban, Tahoe

2000-05 GMC Sierra, Yukon, Yukon XL, Yukon Denali

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:
Dealer or customer may comment that they have a buzz or vibration noise emanating from the headliner in an area that looks like microphone or a speaker.

Recommendation/Instructions:
The plastic escutcheon grill, which is round and about the size of a half dollar and located just above the driver to the left, is the interior ambient temperature sensor. The sensor is used in conjunction with the automatic HVAC (C68). On occasions, this sensor has been known to make a buzz or rattle sound. The sensor uses a small fan to pull air over the sensor. This buzz noise may be intermittent.

Although it may not be possible to alleviate all of the buzz or noise from this sensor, Engineering has found that if the sensor is installed incorrectly that it may bind and cause the fan to make a buzz noise. Remove the sensor and while doing so check for any binding. Reinstall the sensor and re-test. If the noise is still present, the sensor itself may be noisy and require replacement.
