5 Fuel Consumption. A common sign of a bad accelerator pedal position sensor is a decrease or increase in fuel efficiency. When the pedal position sensor fails, it sends an incorrect signal to the engine control module, causing the engine to receive either too much or too little fuel. This will result in poor (or better) fuel consumption.
Agas-powered engine needs three primary ingredients to run: spark, an air-fuel mixture, and compression. When the CKP sensor fails, the PCM doesn't know when to fire the spark plugs and pulse the fuel injectors. Bad Throttle Position Sensor Symptoms: What You Need to Know.

HOWTO TELL WHICH TPMS SENSOR IS BAD demonstrated on FORDIf you have Ford and you have TPMS light / tire pressure light on your Ford because of a bad sensor
Educationalvideo on how the Throttle Position Sensor (TPS) works and how to test for proper operation using a digital volt meter and a Digital Storage Oscil
Ifyou think your throttle position sensor is failing, working some of the time and other times it is registering negative percent, my first suspicion: RF Interference. Not that your TPS can't fail. But the failure tends to be deterministic, not random. And just as it stalls you look down and see a TPS reading of -22%, that's a pretty good clue. Usuallya bad or failing idle control valve will produce a few symptoms that can alert the driver of a potential issue. 1. Irregular idle speed. One of the most common symptoms commonly associated with a problematic idle air control valve is irregular idle speed. The idle air control valve is programmed to regulate and maintain the engine idle Themost common symptoms of a bad or failing throttle body include rough idle, rough acceleration, a check engine light, engine misfires, or a stalling engine. You may also notice that your fuel consumption has changed or your car's idle fluctuates. If you are still interested in more in-depth knowledge about each symptom, here is a more BadThrottle Position Sensor Symptoms. A bad throttle position sensor can give inaccurate readings or no readings at all, and this can cause shifting issues with an automatic transmission. The problem comes from the fact that many vehicles these days are controlled by a computer called the engine control unit (ECU). Kndsc.
