DTC P0130 Lambda Sensor Circuit Failure (4JJ3 with DPD)

1. Engine control system check

Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 with DPD) Diagnostic system check-engine controls".

2. Current DTC check

1) Connect the scan tool.

2) Turn OFF the ignition switch for 1 minute or more.

3) Start the engine.

4) Operate the vehicle under the conditions for running the DTC.

5) Observe the DTC information with a scan tool. Is a DTC set?

Yes

=>Go to Inspection for open circuit and short circuit in heated oxygen sensor pump current circuit.

No

Go to Intermittent conditions of engine.

Refer to "202.Engine 15D.Symptom(4JJ3 with DPD) intermittent conditions of engine".

3. Inspection for open circuit and short circuit in heated oxygen sensor pump current circuit

1) Turn OFF the ignition switch.

2) Disconnect the heated oxygen sensor harness connector (E66).

3) Inspect the pump current circuit between the ECM (pin 22 of E2) and the heated oxygen sensor (pin 1 of E66) for the following. Is the result normal?
