Hi there - your instincts are good! I suspect a failing crankshaft position sensor as well. When they fail, there is often no Check Engine indicator. Checking for spark at the plugs during a "no start" event would be helpful...
The P means powertrain. The second P is not normal and may just be the scanner you are using. This vehicle does not use the second letter P. I would disregard it. As far as the P0306 it indicates a...
From what you've described, it sounds like a belt broke. All of those systems are belt-driven. A visual inspection would easily confirm this. Don't try to start your engine, as overheating is the main risk for your engine now. I'd...
The most likely cause is a dirty throttle body. The throttle body controls the amount of air the engine is getting. Your engine is drive by wire meaning there are sensors in the accelerator pedal, and a motor controlling the...
Hi there. This is typically caused by warped rotors. When the rotors are warped, the steering wheel will shake when applying the brakes. This is a common issue. I usually measure the rotors to see if they are good, but...
Hey Pete, thanks for writing in. The replacements have more to do with what is actually wrong with the vehicle. If they have been modified illegally, then the answer is an automatic yes. Not only does it cause issues with...
Hello. The symptoms you describe can be caused by many things. If your vapor canister is having known issues then I would start there, as the vapor canister is tied into the vehicle's fuel system and can affect its performance....
As you may know know, a misfire can be caused by many different things ranging from a faulty ignition coil, to bad spark plug wires, bad spark plugs, a faulty crankshaft position sensor, a lean fuel condition which could be...
Hi Robert. Thanks for the question tonight. When these two lights illuminate or flicker like you've described, it usually indicates that a sensor or electrical connection to a sensor that monitors these systems. There are several of these sensors on...
Manual transmissions are directly geared and so a fault in the transmission itself will not cause "fluctuations" in engine RPM. However, a malfunctioning clutch pressure plate and/or contaminated clutch friction material could be a cause of RPM excursions. Fluctuating engine...
This is a very interesting problem. Usually cars are harder to start when cold. There are many reasons why this could happen. The most likely cause is that one of the electronic modules or sensors are starting to break down...
Hi there. That squealing noise that stops when you apply the brakes will turn into a grinding noise eventually. That is the wear indicator to let you know that the brake pads are worn to the point of needing replacement....
This is not normal and you most likely have an engine misfire from a bad plug or ignition coil. Have the engine computer scanned to see what cylinder is misfiring and then you can isolate what cylinder is having the...
Hi there. Go to the brake pedal and look at the top of the leg of the pedal and you will see a switch that is mounted on the bracket that the pedal is hanging off of. That switch is...
Hello, there are two possibilities for why your truck is doing this. The first possibility is that your catalytic converter is severely clogged. If this is the problem, the car will start, but once the catalytic converter reaches operating temperature...
Hi there. I understand how frustrating things like this can be. Base on what you've described, the year, and mileage of the vehicle it sounds like your battery has gone weak or failed internally. A good battery test with a...
Hello, thank you for writing in. The vehicle has detected an issue with the electronic throttle system. The system is designed with sensors and monitors that let you know when there is an issue, and the send you into "limp...
It sounds like your mode door actuator may have failed. The mode door actuator is responsible for controlling the mode door. The mode door is a door inside your dash that will open and close to certain points to guide...
Coolant can leak from dozens of places on a vehicle. The best way to pinpoint a coolant leak is to perform a cooling system pressure test. A qualified technician from YourMechanic will be able to perform this test for you....
When the engine cranks but does not start, this is usually related to a fuel or ignition issue. Since this engine has a distributor, I would recommend checking the distributor, distributor cap, and rotor for any damages. Then I would...
Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car's ECU. When the ECU...
If the oil pressure light is on, it is best not to run the engine. If the warning light really reflects low pressure, then there is inadequate oil to the engine bearings and other parts. A quick test using a...
