2004 Gmc Canyon Runs Funny When Low on Gas
Diagnose and Fix Problems with the 1st Generation GMC Canyon
The 1st gen GMC Canyon was first introduced in 2004 by General Motors to replace the GMC S-15/Sonoma and the Chevrolet S-10. Some people refer to it as the glamorous counterpart of the Chevy Colorado. Like most cars and trucks, there are common GMC Canyon problems that are unique to the model.
Top 5 Problems GMC Canyon 2004 to 2012
Top 5 Problems of the 1st Gen GMC Canyon Truck (2004-2012)
1. Timing Chain
The timing chain is located inside the motor. It connects the bottom engine internals to those at the top. Like in most vehicles, it functions the same way a timing belt does. Its only advantage is that it lasts longer. This is, of course, if you change your oil regularly with high-quality engine oil and ensure it stays at par.
The timing chain in the first-generation GMC Canyon tends to break. This prevents the engine from starting. If it happens while you're driving, it can cause the pistons to get into contact with the valves and get damaged. The valves could also bend and cause further damage to the engine.
When repairing your timing chains, remember to pay attention to the camshaft phaser actuator. It's located on the camshaft and works to send pressurized oil on one side or the other. If it fails, it will cause the same problems you'll experience when the timing chain goes bad.
2. PCV Hose
The PCV hose is located under the hood just behind the intake. In GMC Canyon models where it's made of rubber, it gets brittle and cracks. Sometimes, it can collapse altogether. This then results in a drivability issue or an engine that's running rough.
Your check engine light will generate a P0300 and P0171 code. These represent a fuel trim issue. The only way to fix this problem is to replace the PCV hose. You may need to take the plenum off to access it and solve the problem in your 2004-2012 GMC Canyon.
3. Low Idle Speed
At low idle speed, your engine is forced to raise the RPM's on a launch. This means that it will need to work more than required to get your car moving. The most common cause behind a low idle speed in the first-generation GMC Canyon is a dirty throttle body.
The check engine light will generate the code P0506. You'll need to remove the intake snorkel and throttle body as well. This will allow you to effectively clean the throttle body. If it's too badly off, you may need to replace it.
4. EVAP Vent Valve
The EVAP vent valve is located under the vehicle just above the spare tire and next to the canister. It is the part of the emission system that helps to prevent fuel vapor from reaching the atmosphere. When damaged, you'll get a check engine light with the code P0450 or another EVAP code.
The common problem that plagues these valves is the accumulation of debris. This prevents them from opening or closing properly. The only solution to this is to replace the EVAP vent valve in your GMC Canyon. It's also good to check that your gas cap is not loose or worn out because this can also cause the same problem.
5. Blower Motor Resistor
If you ever try to get some air from your air conditioning system and nothing comes out, you may have a bad blower motor. The same applies if you don't get any hot or cold air or have settings that don't work. You'll need to replace the resistor which is located right next to the blower motor.
It has wires attached to it that could be worn out. The resistor could also be burnt out due to the amperage that's coming from the motor. You'll need to check the motor as well if that's the case. Sometimes, you may have a melted connector that may need to be replaced. Be sure to check out any of these parts at 1A Auto.
