OBD-II trouble codes, including all codes that refer to oxygen sensors, do not constitute a diagnostic or identification of specific failed parts. Consequently, you cannot use the codes as the sole basis to replace vehicle parts. Codes are clues only....

The flashing check engine light signifies misfiring and the engine fault(s) causing the misfiring are probably related to the loss of power you are describing. Misfiring is potentially very damaging and so you should drive at a lower speed to...

If the hazard warning lights use the same bulb (filament) as the turn signals, then yes it can't be the bulbs. I would test the turn signal flasher unit. Basically, you want to test for power to the flasher unit...

The main cause of engine stall on this particular model vehicle is the mass air flow sensor. Normally, this will generate a code on the ECM, that can be detected with a scan tool. The MAF sensor generates a waveform...

Hi Rufus. Thanks for contacting us today. Of the three codes you've provided us tonight, the one that I would place most of my focus would be the crankshaft position sensor. In some cases, when the electrical harness of this...

This sounds like something is broken in the column. A defective lock cylinder, or a seized ignition switch. It would have to be disassembled to see the problem. A qualified mechanic from YourMechanic can come out and diagnose why your...

This may be a result of a dirty or failing idle air control valve. The idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds...

You may have a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. Since...

The flapping noise may have been the serpentine belt breaking. Once the belt broke completely both the water pump and alternator stopped turning, thus accounting for both the overheating the charging light coming on. In all probability you just need...

If you did not bleed the cooling system after performing the repair, there is probably air in the system. Air can be bled by running the engine with radiator cap removed and a special funnel installed, or by using a...

Hi Dorian. Thanks for contacting us today. The mass air flow sensor itself is an on or off type of component, meaning it either works or it won't. It doesn't take time for the sensor to 'break in'. The issue...

There could be several reason why your car is smelling like gas. Your car's spark plugs (https://www.yourmechanic.com/services/spark-plugs-replacement) could be very worn out and not firing properly, causing the gas not to be burned properly and creating a gas smell in...

Hi. Well it sounds like you may have a bad fuel pump. The age of the car would bring me to this conclusion. They will typically last around 150,000 to 250,000 miles, but sometimes less. First, I would have a...

This may suggest a blown head gasket. When this happens, the cylinder head gasket fails which can cause coolant to leak into the combustion chamber causing it to be ignited with the fuel. This is what causes the light colored...

You may have a coolant leak from the water pump seal due to a bearing being bad. This would account for the leak and noise you are getting. I would recommend not driving the vehicle until this is diagnosed and...

Hi There, I believe you may be on the right track in terms of the starter gear not disengaging from the flywheel quick enough upon start up. This can happen for a couple of reasons. Either the starter solenoid itself...

Cold weather causes plastic and rubber components to contract. The intake manifold on my truck would expand and contract every winter, setting P0171 and P0174 lean codes. Then finally, this past winter, the manifold cracked (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-intake-manifold-gaskets). My guess is that...

The ignition system on these cars is a very common problem causing no starts. The fuel pumps are the next most common problem causing the no start. My suggestion is to have a qualified technician check the ignition and fuel...

Hi there. From the description you have provided, there are several things to address concerning your vehicle overheating. Given the location described, it could be, the bypass hose that blew (https://www.yourmechanic.com/services/radiator-hose-replacement). This could be the result of hose degradation, which...

The are dozens of potential causes for your issue. Since the problem goes away after the vehicle sit and cools down, my guess is that the problem is electrical. This is because electrical resistance goes up when heat increases. When...
