DTC 35 Turbo Pressure Sensor Circuit Barometric Pressure (BARO) Sensor Circuit

CIRCUIT DESCRIPTION

HINT DTC 35 is used to indicate malfunctions in the turbo pressure sensor circuit or BARO sensor circuit.

1. TURBO PRESSURE SENSOR

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.
If the ECM detects the below diagnosis conditions, 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.

DTC No. | Circuit | Diagnostic Trouble Code Detecting Condition | Trouble Area
35 | Turbo Pressure Sensor | Open or short in turbo pressure sensor circuit for 0.5 sec. or more | • Open or short in turbo pressure sensor circuit
• Turbo pressure sensor
• ECM

2. 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. 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).

DTC No. | Circuit | Diagnostic Trouble Code Detecting Condition | Trouble Area
35 | BARO Sensor | Open or short in BARO sensor circuit for 0.5 sec. or more | • ECM
