trouble codes

A few different components could be causing your issue. Your symptoms sound at first like a spark issue. If a plug was tightened down too hard, the gap can become smaller than intended. This would decrease the power of the...

This vehicle engine has a manual throttle cable and cannot accelerate by itself. You may have a faulty idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) that can cause a high idle but is limited to only about 1250 rpm. I would recommend...

If you are still getting the P0720 code (https://www.yourmechanic.com/article/p0720-obd-ii-trouble-code-output-speed-sensor-circuit-malfunction-by-brady-klopfer) after replacing the sensor then you should verify the wiring connection first to the sensor and also in between the sensor and ECM. Remove the sensor and turn the drive shaft....

The throttle position sensor (https://www.yourmechanic.com/parts/throttle-position-sensor) is a very common part on most cars, however it is specific to your vehicle's engine application. This is something that ca be purchased at most local auto parts stores (i.e. Autozone, Oreily's, etc.) relatively...

At 180.000 miles, it could be just about anything. The P0161 and P0140 codes are oxygen sensor codes, and probably don't have anything to do with the starting issue, though you should have that investigated (https://www.yourmechanic.com/services/air-fuel-ratio-sensor-replacement). The P0300 code however...

Code P0120 (https://www.yourmechanic.com/article/p0120-obd-ii-trouble-code-tps-a-circuit-malfunction-by-jay-safford) relates to the throttle position sensor and can be caused by the following: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing Bad TPS Bad PCM Code P0220 (https://www.yourmechanic.com/article/p0220-obd-ii-trouble-code-throttle-pedal-position-sensor-switch-circuit-b-malfunction-by-andrew-quinn) relates to the throttle...

Hello, thanks for writing in about your Ford F-150. I'm curious if you got the new PCM from the dealer. You should check if have the exact same part number on it. If the part numbers do not match and...

Hello. A no start condition can be caused by a wide variety of issues, and from what you describe it would appear that the vehicle may have more than one issue. If spraying brake cleaner into the intake helped it...

This could be a variety of things ranging from a fuel delivery problem to a no spark problem. The good thing is you know you are getting power to the starter if it cranks. Outside of this you will need...

After some testing done to verify the EGR valve flow to see if the valve is intermittently sticking open causing the stall. This can be done using a scanner with the capability to open and close the EGR valve and...

You should have the vehicle scanned for codes (https://www.yourmechanic.com/article/what-is-the-on-board-diagnostics-obd-system) to see if you have codes to the camshaft or crankshaft sensors. Either of these may cause the no spark condition. If the fuel pump regulator is bad, then you would...

It is usually best to change all the coils when chasing a misfire with engines of this age and mileage. If one is weak, they are likely all weak. When you changed the plugs, was there oil in the spark...

It could very well be a timing chain problem (https://www.yourmechanic.com/services/timing-chain-replacement). The P0016 and 17 indicate that the camshaft sensors (https://www.yourmechanic.com/services/camshaft-position-sensor-replacement) are sensing the camshaft in a position that does not logically correspond with the crankshaft. The P0302 (https://www.yourmechanic.com/article/p0302-obd-ii-trouble-code-cylinder-2-misfire-detected-by-jamahl-walker) and P0355...

Anytime you go to a parts store to get a computer scan for the Check Engine Light (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection) you are not getting a diagnosis of the problem but only a code retrieved from the engine control module (ECM) memory. This...

Hi there: The EVAP system is comprised of multiple components. Although the gas cap removal is the easiest job to complete and the source of many of these problems, another common issue is caused by the EVAP vent solenoid (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-evaporation-vent-solenoid)....

In this case you will need to have the computer scanned to retrieve the codes that are stored. The codes will indicate the exact problem areas. Have the trouble codes and warning light diagnosed (https://www.yourmechanic.com/services/warning-light-is-on-inspection) by a certified technician, such...

A vehicle with 182,000 miles is likely due for a catalytic converter. Most of the time it does mean you need a new catalytic converter. But there are a couple of other things that are prudent to take a look...

When a truck won't start, it's usually going to be an ignition or fuel system-related malfunction. The fact that your gas gauge was "ticking" a bit may be an indicator that an electrical problem exists, causing the ignition system to...

Hello. the Diagnostic Trouble Codes would have to be retrieved to begin the diagnosis. Unless the shop retrieved all codes and performed a diagnosis and tested the coils (there are six of them on your engine), what they have told...
