Powertrain

Puedes seguir conduciendo con precaución

Descripción

This code means the engine's computer has detected a mismatch between the readings from the Mass Air Flow (MAF) or Manifold Absolute Pressure (MAP) sensor and the Throttle Position Sensor (TPS). These sensors should normally correlate.

Causas comunes

  • Dirty or faulty Mass Air Flow (MAF) sensor
  • Vacuum leak
  • Faulty Throttle Position Sensor (TPS)
  • Problem with the Manifold Absolute Pressure (MAP) sensor
  • Clogged air filter

Síntomas

  • Check Engine Light is on
  • Rough idle
  • Hesitation during acceleration
  • Poor fuel economy
