DTC P007D-00: Boost Air Temperature Sensor Circuit High Input

P007D:00 (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Boost air temperature sensor circuit high input
Detection condition	The PCM monitors the boost air temperature sensor signal. If the PCM detects that the boost air temperature sensor voltage at the PCM terminal 1BI is standard or more, the PCM determines that the boost air temperature sensor circuit has a malfunction.
Fail-safe	Not applicable
Possible cause	Boost air temperature sensor malfunction (Refer to BOOST AIR TEMPERATURE SENSOR INSPECTION (VIN Y) in the service information.) Malfunction in wiring harness (including connector/terminal) between PCM and boost air temperature sensor (see CIRCUIT INSPECTION .) (see CONNECTOR INSPECTION .) PCM malfunction (Refer to applicable PCM REMOVAL/INSTALLATION (VIN Y) in the service information.)
Repeatability verification procedure	Clear the DTC recorded in the memory. (see CLEARING DTC .) Perform the KOEO or KOER self test. (See DTC INSPECTION .)
