What is the P0302 Code?

The P0302 code is a diagnostic trouble code (DTC) that indicates a misfire in cylinder 2 of your Toyota Tercel's engine. When the engine control module (ECM) detects that the engine is not firing properly in this specific cylinder, it triggers the P0302 code.

Common Causes of P0302

Several factors can lead to a P0302 code in your Toyota Tercel. Here are some of the most common causes:

  1. Faulty Spark Plug: A worn or damaged spark plug can prevent proper ignition in cylinder 2.
  2. Ignition Coil Issues: A malfunctioning ignition coil can lead to a misfire by failing to deliver the necessary voltage to the spark plug.
  3. Fuel Injector Problems: A clogged or faulty fuel injector can restrict fuel flow to cylinder 2, causing a misfire.
  4. Vacuum Leaks: Leaks in the intake manifold or vacuum hoses can disrupt the air-fuel mixture, leading to misfires.
  5. Engine Mechanical Issues: Problems such as low compression or valve issues can also cause misfires.

Symptoms of P0302

When your Toyota Tercel triggers the P0302 code, you may notice several symptoms, including:

  • Rough Idling: The engine may run unevenly or shake while idling.
  • Decreased Power: You may experience a noticeable drop in engine performance and acceleration.
  • Check Engine Light: The check engine light will illuminate on your dashboard.
  • Increased Fuel Consumption: A misfire can lead to inefficient fuel usage, resulting in higher gas bills.
  • Engine Stalling: In severe cases, the engine may stall or have difficulty starting.
