DATA TROUBLE CODE: 35SYSTEM: A. Turbo Pressure Sensor Circuit
OR
B. Barometric Pressure (BARO) Sensor
CIRCUIT WIRING DIAGRAM
CIRCUIT DESCRIPTION
A. Turbo Pressure Sensor Circuit
This sensor detects the air intake chamber pressure and converts the pressure reading into a voltage which is used to control the turbo pressure by the ECM.
NOTE: If the ECM detects the conditions described below, it operates the fail safe function in which the ECM stops fuel injection at engine speed 2,400 rpm or more and throttle opening angle 20° or more.
DIAGNOSTIC TROUBLE CODE DETECTING CONDITION
- Open or short in BARO sensor circuit for 0.5 sec. or more.
TROUBLE AREA
- Open or short in turbo pressure sensor circuit.
- Turbo pressure sensor.
- ECM.
CIRCUIT DESCRIPTION
B. Barometric Pressure (BARO) Sensor
This sensor is built into the ECM. It is used to detect the atmospheric (absolute) pressure and outputs corresponding electrical signals. Fluctuations in the air pressure cause changes in the intake air density which can cause deviations in the air-fuel ratio. The signals from BARO sensor are used to make corrections for the fluctuations.
NOTE: If the ECM detects the below diagnosis conditions, it operates the fail safe function in which the atmospheric pressure is assumed to be 101.3 kPa (1.03 kgf/cm2, 14.7 psi).
DIAGNOSTIC TROUBLE CODE DETECTING CONDITION
- Open or short in BARO sensor circuit for 0.5 seconds or more.
TROUBLE AREA
- ECM
