20 Most Recent 2005 GMC Canyon Questions & Answers

Hi there:Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.Symptoms may include:the engine may be harder to startthe engine may stumble / stumble, and/or hesitateother symptoms may also be presentA code P0300 may mean that one or more of the following has happened:Faulty spark plugs or wiresFaulty coil (pack)Faulty oxygen sensor(s)Faulty fuel injector(s)Burned exhaust valveFaulty catalytic converter(s)Stuck/blocked EGR valve / passagesFaulty camshaft position sensorDefective computerPossible Solutions: If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

Question edited for clarity. Question moved to model category. Video help is the best way.

Could be any number of thing's . Engine management system sensors . Anything mentioned on here would be a guess . Having a qualified repair shop with the proper testing equipment viewing sensor scan data is the way to a fix . Not going by peoples guess . It could be a fuel system or ignition system prblem , engine sensor etc.... 047 Engine Hard to Start or No Start Scan Data for Ignition 048 Engine Hard to Start or No Start Scan Data for Starting Problems Takes year's to learn how to properly diagnose these systems . I have over thrity year's experience , thousand's of dollars of scan tools , diagnostic equipment etc... An ever year they come of with new stuff , I go to GM tech school 4 or 5 times a year .

The engine compartment fuse block is located on the driver's side of the engine compartment Check fuses 21 and 42. https://my.gmc.com/content/dam/gmownercenter/gmna/dynamic/manuals/2005/gmc/canyon/2005_gmc_canyon_owners.pdf

hello, with out more info it sounds like it could be the drive axle could be going bad if it's a 4x4 or possibly one of the pins holding the brake caliper in place has backed out and rubbing the inside of the wheel. I would also check the wheel bearings to make sure the wheel is not loose and making the noise you hear.

check the fuses in the underhood fuse box?! could be more than one bad one.

The problem with most newer vehicles is that many functions are controlled by computer modules which are prone to malfunction when spikes occur in the electrical system. Often this is a temporary condition and the computers can be reset by disconnecting the negative battery cable for a few minutes and then reconnecting it. However, if the problem is persistent or keeps occurring, the faulting module (in your case the TC module) will need to be replaced. Most GM vehicles have a button in the vehicle that will disable the system (see the owners manual), but if one is not is available or is not working properly, check out https://www.youtube.com/watch?v=TUoV2ue7amY.

Checking the 4X4 control module for DTC'S - diagnostic trouble codes is what you should done . Need a factory or professional type scan tool , no an OBD2 code reader . Looking at factory service repair info. description of how it works , an testing is how to diagnose . Not guessing an throwing parts at it . DTC B2725 The accessory switch circuit consists of 4 modes. The transfer case shift control module supplies 5 volts to the switch through the switch signal circuit. The current travels through the resistor of the currently active mode. The current on the switch signal circuit is monitored by the transfer case shift control module. The voltage on the switch signal circuit will vary depending on which mode button is pressed by the driver. The transfer case shift control module constantly monitors the switch signal circuit to determine the condition of the accessory switch circuit. When each of the modes are selected they complete a circuit through their own specific resistor. The transfer case shift control module continuously monitors the switch signal circuit to determine whether the Neutral, 2HI, 4HI, or 4LO mode was selected by the driver. DTC C0327 Encoder Circuit Malfunction The transfer case shift control module has 4 encoder circuits, and each circuit is supplied 12 volts. These 4 circuits are A, B, C, and P, and each circuit runs to a switch located inside the encoder/motor assembly. When a particular encoder circuit is active, the switch is closed, and the 12 volts are grounded by the switch inside the encoder. The transfer case shift control module supplies 12 volts on all the circuits. The module can interpret the location of the transfer case shift position when the circuits are grounded. This DTC detects a fault when it compares the shift sequence/strategy to a chart located in read only memory (ROM), within the electronic control unit (ECU), within the transfer case shift control module. This is accomplished by the module reading the different combinations of encoder signals being grounded while others remain high depending on what mode or range the transfer case is in. DTC C0550 ECU Malfunction At each power-up, the transfer case shift control module runs a self-test on the following functions: • EEPROM Checksum • ROM Checksum • RAM Checksum • RAM Malfunction I suggest your take your vehicle to a qualified repair shop .

It will only crank to start in neutral or park. If you turned the switch off before you put in park, the shifter will not move up to get in either. Turn the switch on, put it in park, then turn the switch off. The key won't even come out if not in park. Safety features can sometimes be a pain, but they work.

What size engine?

hello you could have a bad light switch, and the rheostat that operates the dash lights may not always work if weak connection.also the wiring may have gotten hot and the contact to the wiring is intermittent, check close to the switch connector to see if the wiring has turned colors from heat ? if so then you will have to change the connector with the electrical ends and the light switch.

hello, If the frt brakes are locked up then it could be any of the following, master cylinder is bad, frt brake lines are at fault the flexible rubber part that goes to the calipers, or the calipers themselves could be frozen and are not able to release when you let off the brake pedal.
