2007 avalanche what wires do I splace in maf

I assume you are referring to the Mass Air Flow (MAF) sensor in a 2007 Chevrolet Avalanche.
The MAF sensor has a wiring harness connector that connects to the sensor. If you need to replace the MAF sensor or the wiring harness, it is important to ensure that you connect the wires correctly to avoid any damage to the sensor or your vehicle's electrical system.
Here are the steps to replace the MAF sensor or wiring harness in a 2007 Chevrolet Avalanche:

Locate the MAF sensor on your vehicle. It is typically located in the air intake system between the air filter and the throttle body.
Disconnect the wiring harness connector from the MAF sensor by pushing down on the release tab and pulling the connector away from the sensor.
If you are replacing the wiring harness, connect the new wiring harness to the MAF sensor by aligning the pins and pushing the connector into place until it clicks.
If you are replacing the MAF sensor, connect the wiring harness to the new MAF sensor by aligning the pins and pushing the connector into place until it clicks.
Ensure that the wiring harness is securely connected to the MAF sensor.
Start the vehicle and check for any warning lights on the dashboard.

Note: The specific wiring colors for the MAF sensor on a 2007 Chevrolet Avalanche may vary depending on the engine size and other factors. If you're unsure about the wiring, it's always a good idea to consult a mechanic or refer to the vehicle's repair manual.

Hi, looking for a ECM wiring diagram on a Chevy Captiva 3.2 2007. Please

Your question is a little broad. Can you tell us the problem? If your having a problem with ignition or fuel system, something like that, I can help with wiring diagrams. If you need voltage and ground for pcm, I can't help with that. Can you narrow the problem down, a little?

To post a diagram of every little wire that comes off the pcm and show where it goes, is too much for me.

2002 chev avalanche mat sensor

I assume you are looking for the wiring for the IAT because MAT sensors are no longer used..

here you go

black / white - PCM ground
pink - fused 12-volts
yellow - MAF signal
tan - IAT sensor signal
black - IAT sensor ground

manifold temp. sensors are no loner used.

I believe you are looking for the IAT "intake air temp sensor" which is part of the mass air flow sensor.

good luck

Yeah that info is super hard to come by. You should be able to match color codes together. Just make sure you check stripe color as well. All data is the best source in fact most repair shops and dealers use their service. It is a pay site but you can do a either 1 month or 1 time (i forget whch) subscription. They detail everything as their info comes from the dealer service manuals.
