INSPECTION PROCEDURE
HINT:
D
If DTCs "P0110" (Intake Air Temp. Circuit Malfunction), "P0115" (Engine Coolant Temp. Circuit Mal-
function), "P0120" (Throttle/Pedal Position/Switch "A" Circuit Malfunction), "P1410" (EGR Valve Posi-
tion Sensor Circuit Malfunction) are output simultaneously, E2 (Sensor Ground) may be open.
D
Read freeze frame data using TOYOTA hand–held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air–fuel
ratio lean or rich, etc. at the time of the malfunction.
1 Check voltage between terminal VC of wire harness side connector and body
ground.
