A MAP sensor can cause rough running, hesitation, poor acceleration, stalling and check-engine lights when its pressure signal is inaccurate. But replacing the sensor based only on a symptom or trouble code is a common diagnostic mistake. The better approach is to...

A mass airflow sensor, or MAF sensor, tells the engine computer how much air is entering the engine. When its reading is wrong, the engine can develop rough idle, hesitation, poor acceleration, stalling, poor fuel economy, or a check-engine light. But don’t...

Replacing rear brake pads is a job many experienced DIYers can handle, but rear brakes have one important complication that front brakes often don’t: the parking-brake mechanism. Some vehicles use a conventional mechanical parking brake, while many newer cars...

A failing transmission input speed sensor can cause hard or erratic shifting, delayed gear changes, limp mode, warning lights, and unusual engine RPM behavior. The sensor provides the transmission computer with information about how fast the transmission’s input...

If your transmission pressure sensor is failing, you may notice hard or delayed shifting, slipping, a transmission warning light, or limp mode. But those symptoms do not prove the sensor itself is bad. Wiring problems, low or contaminated fluid, solenoid faults,...
