Monitored & Set Conditions

Throttle Position (TP) sensor circuit is monitored with engine running and no Manifold Absolute Pressure (MAP) sensor or Throttle Position (TP) sensor DTCs are set. The DTC set condition is set by the PCM which determines a valid range in which the TP sensor should be, at a given RPM/Load. The actual TP sensor voltage is then compared to this value. If the TP sensor voltage does not fall within the expected range within a predetermined time an error will be detected. This is a one trip fault.
