SOURCE: How do I do an oil change for 2006 GMC Canyon?

Lift your GMC Canyon using a jack and set the truck on jack stands. If you don't have jack stands then use a set of wheel ramps. Make sure you brace the front tires so the truck doesn't roll. (safety first) Pop the hood and take off the oil filler cap and remove the dipstick. Gather an oil drip pan, cleaning cloths, new oil filter, and adjustable crescent wrench and then slide under the truck. Locate the oil drain plug and filter. Loosen and then remove the oil plug and pull it out quickly. Let the used oil drain for 10 to 15 minutes into the drip pan. Take off the filter using an oil filter wrench. Check the gasket and threads for damage and dump the extra oil into the drip pan. Clean off any excess oil and replace with new oil filter. Put the oil drain plug back in (tighten it) and slide out from underneath your truck. Add new oil (approx 5 quarts) inside the oil filler hole and replace the dipstick and then tighten the oil cap. Lower your truck and start the engine for a minute so that oil pressure builds up. After you are done with the oil change, turn the ignition key to "run" and then hit the gas pedal three times to reset the oil change light.

I own a 2008 GMC Envoy Denali, 2WD. Yesterday the engine would barely idle and numerous lights on the dash came on including the check engine light. I had a friend check the diagnostic codes and it came up...

Five days prior to this, the battery had to be replaced. The engine was started without the pause for two minutes ?????? Where do you people come up with some of this stuff ? Pausing for two min. before starting has nothing to do with it . DTC P0651: 5-Volt Reference 2 Circuit
Some of the engine sensors on your vehicle work off of a steady 5 volt supply by the PCM - engine computer . One of these sensors is short internally bring down the PCM .
Short to Ground
Open/High Resistance
Short to Voltage
Signal Performance
Accelerator Pedal Position (APP) Sensor 1 5-Volt Reference 2 Circuit
Accelerator Pedal Position (APP) Sensor 2 5-Volt Reference 1 Circuit
Air Conditioning (A/C) Refrigerant Pressure Sensor 5-Volt Reference 1 Circuit
Camshaft Position (CMP) Sensor 5-Volt Reference 1 Circuit
Engine Oil Pressure (EOP) Sensor 5-Volt Reference 1 Circuit
Fuel Tank Pressure (FTP) Sensor 5-Volt Reference 1 Circuit
Manifold Absolute Pressure (MAP) Sensor 5-Volt Reference 1 Circuit
The Crankshaft Position (CKP) Sensor 5-Volt Reference 2 Circuit
Throttle Position (TP) Sensor 1 and 2 5-Volt Reference 2 Circuit
P0122, P0222

That's why it wasn't running good ,an lights lit on the dash. Your best bet , take it to GMC dealer .
No where in GM service info does it say after replacing the battery that you need to wait two min. before starting .
Position the positive battery cable (1) to the battery.
Tighten the positive battery cable bolt.
Tighten the bolt to 15 N·m (11 lb ft).
Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2006 gmc canyon will not go into 4 wheeldrive after 5 minutes of driving

The first place to start is have it checked for codes an to see if a scan tool will communicate with the 4X4 control module !
Diagnostic Starting Point - Transfer Case
Begin the system diagnosis with the Diagnostic System Check - Vehicle . The Diagnostic System Check will provide the following information:
The identification of the control module or modules that command the system.

The ability of the control module or modules to communicate through the serial data circuit.

The identification of any stored diagnostic trouble codes (DTCs) and the status of the codes.

The use of the Diagnostic System Check - Vehicle will identify the correct procedure for diagnosing the system and where the procedure is located.
Install a scan tool.
Does the scan tool power up?
Go to Step 3
Go to Scan Tool Does Not Power Up


  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to establish communication with all of the control modules on the vehicle. Refer to Scan Tool Does Not Communicate with Class 2 Device for the modules you should expect to observe.
Does the scan tool communicate with all of the expected vehicle control modules?
If you don't have a scan tool that will communicate with all modules on the vehicle or understand this , your best bet is to take it to a ASE certified repair shop or the dealer .

Locked radio 2006 gmc canyon

Most modern cars have a security code enable for the installed radio/cd players. This is an anti-theft device.

The initial documents given to the owner when the vehicle was purchased lists this code and how to reset it.

If you are second owner/original owner who has lost this information, then, you can approach gmc canyon dealer and they will have this code on their server. Normally a free service (I believe).

The security code is lost from the radio whenever keep alive voltage is removed from the radio. i.e. You disconnected or replace the battery.

I hope this helps.

My GMC canyon truck 2006 is running very rough. I did a diagnostic test at the part store, and the codes P0300, P0017, P0068, came up. The dash control panel says reduced power.

Code 300 is for a random miss, code 17 is for a problem with the timing between the cam and crank sensors, and code 68 is a problem between where the throttle position sensor is and the amount of air coming into the throttle body.
You may need to research the trouble codes to get the testing procedures. You may also need a scanner to do the tests.

GMC Canyon, computer shot.. cost?

You can to the Salvage Yard for a new computer, but your going to have to get it reprogram to your ignition keys, so the Passlock will start the engine. Before you go through all of that. recheck every thing, it could be your crank sensor or your ICM faulty causing your engine to shut down. Keep me posted and let me know what DTC codes you have. Note: a faulty fuel pump or dirty fuel filter will not set a DTC code. You may have a dirty fuel filter or faulty fuel pump or faulty fuel pump wire harness or fuel pump relay.

2006 Canyon 4cyl has extremely low idle. Autozone Diagnostics gives code:P0506. Idles low if at all.

Could be:
  • A vacuum leak
  • An air restriction in the intake air path or exhuast
  • A faulty positive crankcase ventilation (PCV) valve
  • Damaged/failed/dirty throttle body
  • Internal engine problem
  • Failed PCM (powertrain control module)
I say back to the shop if its a real problem, if at all to just clear the code to see if it comes back. That code is just an informational code. Just says what the car is doing :\ . My first guess would be a vacuum leak somewhere followed by a throttle body issue.
