Q: Hi im having problem with ford fiesta...want reverse but will drive

Hi there. A code P0401 indicates that the EGR system is not working properly. The EGR, or exhaust gas recirculation system, is used for emissions to reduce the NOX emissions. If it's not functioning and opening as it should, then...

This may be a sign of a faulty MAP sensor. The Manifold Absolute Pressure (MAP) sensor senses engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The engine computer then uses...

The heated seat circuit includes wiring, terminations, the switch and possibly a relay. There is the resistive element (heater) in the seat as well. Basically, all of those components would be evaluated in any electrical diagnostic of the fault. If...

Hi there. The problem with trying to diagnose this transmission fluid leak issue you have with the Hummer is that it's quite possible that the leak could be caused by multiple issues. Certainly a loose transmission fluid tube or damaged...

Hello, thank you for writing in. The first thing to consider is your driving habits. If you are consistently braking hard, it can be rough on your brake system and you transmission. The jolt is the biggest cause for concern....

P0123 (https://www.yourmechanic.com/article/p0123-obd-ii-trouble-code-throttle-pedal-position-sensor-switch-tps-a-circuit-high-input-by-jay-safford) and P0222 (https://www.yourmechanic.com/article/p0222-obd-ii-trouble-code-throttle-pedal-position-switch-sensor-b-circuit-low-input-by-andrew-quinn) both implicate the throttle position sensor and circuit. P0562 involves the charging circuit and alternator. These are not particularly difficult codes to resolve as both the charging circuit and the throttle position sensor/circuit can be...

The N80 valve is a "purge valve" located on top of the engine. It is a very simple component in the EVAP system and indeed you can easily replace it yourself. The only way to ensure that the N80 valve...
