The most common causes of Diagnostic Trouble Code P2118 are failure of the throttle actuator control motor, a failed pedal position sensor, a faulty throttle position sensor, an open or short in the actuator circuit, or a poor electrical connection...

The problems you are describing do seem to lead me back to the charging system circuit. If the vehicle shuts down because of a dead battery, the problem has to be in the charging system as it is designed to...

Hi there: In some cases, the wrong or incorrect tightness or alignment of the serpentine belt can cause this type of noise. Since you stated this noise began after this part was replaced, leads me to think that it's either...

Hi there. You should check to see if the fuel pump is turning on when it will not start. This can be done by checking fuel rail pressure or listening for the fuel pump to make noise when you turn...

There are many potential causes for your concern. A misfire results from ignition problems, an incorrect air/fuel ratio or loss of compression. Since you said it only stays running when you give it gas, my guess is that the air/fuel...

Any good mechanic can check them out. Here's the problem that you've got though--when there's a linking error, either the nanoport isn't working right because one of the pins is bent or there's wiring short somewhere in the computer system...

While it is possible that a hose may need to be replaced, it may not be the root cause of your overheating concern. Does it overheat while driving on the highway at cruising speed or in stop and go traffic?...

Hi - by "won't shift into the highest gear", I interpret this to mean the lock-up of the torque converter, which effectively is another gear (eliminates any slip through the torque converter). Your symptoms suggest that the transmission is not...

Every single part on a motor vehicle will eventually fail or "wear out", and often parts will fail multiple times over the vehicle's life (for example, tires, brakes, rotors, water pumps, oil seals, timing belts, bulbs, hoses, and so forth)....

Hi, thanks for writing in. That "debris" you feel is usually clutch material. Clutch material inside automatic transmissions is very similar to manual transmission clutch material as well as brake pad material. It generally appears as a fine dust. While...

From your description, I would say that your clutch is due for a replacement. If there was a mechanical issue inside the transmission, the shifter would be hard to move even with the engine off. Since the clutch assembly is...

Hi There, Code P0506 relates to the idle air control valve, specifically that the idle speed is less than the target idle speed by 100 RPM or more. The idle air control valve monitors the air intake as it is...

This problem could be related to the immobilizer function of the alarm system, or could be related to the engine or vehicle ground circuits. If the Check Engine Light is illuminated, a local mechanic with an advanced scan tool (like...

From your description, it does sound like a worn out clutch. The clutch has a friction material much like brake pads do. This material wears out over time and symptoms like the ones you are describing are typical. The clutch...

Hey there. You cannot operate a motor vehicle on public roadways if you know for a fact that it stalls unexpectedly. So the first order of business is to STOP driving the car especially given the two frankly lurid examples...

Hello. Most of the time this is caused by a programming issue. I have seen these cars need to be re-programmed for issues with the batteries not fully charging in cold weather. If the vehicles computer have not been updated...

Radiator hose collapse is from a leaking intake manifold gasket or radiator cap is bad and not letting the system draw fluid from overflow. Replace the cap and pressure test system to see if it has a leak in the...

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...

Tail lights stay on when the car is off and your brake lights don't work at all. If lights are staying on when you turn the car off, the ignition switch turns power off to that spot. Maybe your ignition...

Hi there. Most of the time when this occurs it is due to a lack of voltage. It can be from a failing battery or alternator. Most of the time the issue is the battery. If the voltage is dropping...

Hello. If you replaced your transmission and the engine is not starting the first thing I would do is to try to make sure the engine is rotating. You can do this by putting a breaker bar onto the crankshaft...

Hi there. We have two great articles posted here on our website that will really help you learn more about the EVAP system and specifically the purge solenoid. The first is this article which explains what the P0455 OBD-II trouble...

The problem is most likely caused by a built in relay inside the TIPM or totally integrated power module or also called main engine fuse box. These go bad all the time and can cause accessory problems like you are...
