What Causes the Engine Malfunction Light to Turn Off After Revving the Throttle?
1 Answers
The reasons why the engine malfunction light turns off after revving the throttle include insufficient fuel in the fuel tank, which fails to achieve normal adsorption pressure. Blockage in the fuel line can lead to reduced fuel pressure and poor acceleration. A faulty throttle pedal sensor may result in driving at only one RPM without response to throttle input. A malfunctioning throttle body can also cause unresponsiveness during acceleration. Inspection: Check the spark plugs, high-voltage wires, and ignition coils. Inspect the fuel pump pressure and check if the fuel injectors are clogged. Also, examine the ignition system for any misfires. Precautions: For an automatic transmission with manual mode, try switching to manual mode and downshifting by 1–2 gears. For a purely automatic transmission, try releasing the throttle slightly before pressing it down firmly again.
