(FLASH CODE 86) BAROMETRIC PRESSURE SENSOR CIRCUIT HIGH INPUT
DIAGNOSTIC TROUBLE CODE (DTC) P1105 (SYMPTOM CODE 2)
(FLASH CODE 86) BAROMETRIC PRESSURE SENSOR CIRCUIT LOW INPUT
Condition for setting the DTC and action taken when the DTC sets
Circuit Description
The ECM monitors the barometric pressure signal at
inside of the ECM. If the sensor with malfunction, DTC
P1105 (Symptom Code 1) or P1105 (Symptom Code 2)
will be stored.
Diagnostic Aids
If the DTC P1105 is stored, sensor or circuit of ECM
inside is failed.
