4 Reasons Why Your Gas Gauge Isn''t Working

· Gas Gauge Failure is less common, but still a possible issue. If the internal circuit is faulty, the gas gauge may only function in one section, such as between HALF and FULL or between EMPTY and HALF. If the internal circuits are shorted, they may peg to FULL or EMPTY. If the circuit is open, the gas gauge will likely sit at EMPTY and never move.

Symptoms of a Bad or Failing Throttle/Accelerator Pedal ...

· The APP sensor essentially tells your engine how fast or slow to drive when you press the gas pedal. When you press down or lift off the throttle, it sends an electrical signal to the vehicle’s engine control unit (ECU), and then transmits that signal to the fuel system. The primary reason why this part fails is due to exposure to high heat, as it''s typically located on the floorboard next ...
