Possible causes – Faulty Heated Rear Oxygen Sensor Bank 2 – Heated Rear Oxygen Sensor Bank 2 harness is open or shorted – Heated Rear Oxygen Sensor Bank 2 circuit poor electrical connection – Fuel pressure – Injectors – Intake
Possible causes – The EGR volume control valve circuit harness is open or shorted – EGR volume control valve leaking or stuck open – Faulty EGR temperature sensor Tech notes Start by cleaning the EGR valve, if the code persist
DTC P0069 MAP sensor and BARO sensor signal correlation error DETECTION CONDITION • The PCM monitors MAP sensor signal voltage at PCM terminal 234 and barometric pressure at PCM internal BARO sensor. If these signals are not plausible, the PCM determines
DTC P0087 Fuel rail pressure – too low DETECTION CONDITION • The PCM monitors the fuel pressure in the common rail from the fuel pressure sensor while the engine is running. If the fuel pressure is less than the threshold, the
DTC P0088 Fuel rail pressure – too high DETECTION CONDITION • The PCM monitors the fuel pressure in the common rail from the fuel pressure sensor while the engine is running. If the fuel pressure is more than threshold, the PCM
DTC P0089 Fuel Pressure Regulator Performance DETECTION CONDITION • PCM detects the fuel pressure at the common rail for the following while the engine is running, the PCM determines that the fuel system pressure is not controlled properly. ― Fuel pressure is
DTC P0097 Intake air temperature (IAT) sensor No.2 circuit low input DETECTION CONDITION • The PCM monitors the IAT sensor No.2 signal. If the voltage at PCM terminal 242 remains low, the PCM determines that there is an IAT sensor No.2
DTC P0098 Intake air temperature (IAT) sensor No.2 circuit high input DETECTION CONDITION • The PCM monitors the IAT sensor No.2 signal. If the voltage at PCM terminal 242 remains high, the PCM determines that there is an IAT sensor No.2
DTC C1194 DSC continuous operation fault DETECTION CONDITION • The PCM receives DSC operation signals from DSC CM while the engine switch is turned to the ON position. If the PCM receives DSC operation signals for longer than the specified time,
DTC P0033 Air bypass valve position sensor open circuit DETECTION CONDITION • The PCM monitors the input voltage from the air bypass valve position sensor. If the voltages at PCM terminal 233 deviates from the threshold, the PCM determines that the
DTC P0045 Variable boost control (VBC) solenoid valve control circuit open DETECTION CONDITION • The PCM monitors the input voltage from the VBC solenoid valve. If the voltages at PCM terminal 104 remain low or high, the PCM determines that the
DTC P0046 Variable boost control (VBC) solenoid valve range/performance problem DETECTION CONDITION • The VBC solenoid valve driver temperature is too high. • The VBC solenoid valve is stuck. POSSIBLE CAUSE • VBC solenoid valve malfunction • PCM malfunction
DTC P0047 Variable boost control (VBC) solenoid valve control circuit low input DETECTION CONDITION • The PCM monitors the VBC solenoid valve control signal. If the voltage at PCM terminal 104 remains low, the PCM determines that there is a VBC
DTC P0048 Variable boost control (VBC) solenoid valve control circuit high input DETECTION CONDITION • The PCM monitors the VBC solenoid valve control signal. If the voltage at PCM terminal 104 remains high, the PCM determines that there is a VBC
