DTC P0035: Turbocharger Bypass Control Solenoid Valve Circuit High Voltage

General Description

Courtesy of HONDA, U.S.A., INC.

The powertrain control module (PCM) controls the turbocharger bypass control solenoid valve to adjust the timing of pressure relief and improves the response of the boost pressure when the vehicle is re-accelerated immediately after the deceleration and reduces the boost pressure during the deceleration as well. The turbocharger bypass control solenoid valve is normally closed (negative side pressure). If the voltage level of the ABV terminal is OFF (high voltage) despite the PCM outputs ON signal to the turbocharger bypass control solenoid valve or if the PCM detects over current of the turbocharger bypass control solenoid valve while the PCM outputs ON signal to the turbocharger bypass control solenoid valve, the PCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type

Execution	Continuous
Sequence	None
Duration	0.5 second or more
DTC Type	Two drive cycles, MIL off

Enable Conditions

Condition	Minimum	Maximum
12 volt battery voltage [Battery]	10.0 V	-
State of the engine	Running

[ ]: HDS Parameter

Malfunction Threshold

Either of the condition occurs:

The voltage level of the ABV terminal is OFF (high voltage) for at least 0.5 second despite the PCM outputs ON signal to the turbocharger bypass control solenoid valve.
The turbocharger bypass control solenoid valve output driver in the PCM detects an over current for at least 0.5 second while the PCM outputs ON signal to the turbocharger bypass control solenoid valve.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Turbocharger bypass control solenoid valve ABV line short to power
Turbocharger bypass control solenoid valve ABV line open
Turbocharger bypass control solenoid valve power supply line open
Turbocharger bypass control solenoid valve failure
PCM internal circuit failure

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, a Confirmed DTC, the freeze data, and the on-board snapshot are stored. The MIL does not come on.

Conditions for clearing the DTC

The Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
