INSPECTION PROCEDURE

HINT:
- If DTCs P0110, P0115, P0120 and P1410 are output simultaneously, E2 (sensor ground) may be open
- Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool, as freeze frame data 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 was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.
