Inspection Procedure

If DTC P0115 and P0116 are output simultaneously, engine coolant temp. sensor circuit may be open. Perform troubleshooting of DTC P0115 first. 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.

Check For Intermittent Problems

By putting the vehicle's ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems. (1) Clear the DTC (See step 3). (2) Set the check mode (See step 3). (3) Perform a simulation test (See page IN-30). (4) Check the connector and terminal (See page IN-41). (5) Handle the connector (See page IN-41).

Check for open and short in harness and connector between ECM and oxygen sensor See page IN

(a) Connect the OBD II scan tool or TOYOTA hand-held tester to the DLC3. (b) Warm up the engine to normal operating temp. CHECK Read voltage output of oxygen sensor when engine suddenly raced. HINT Perform a quick racing of 2,000 rpm or more 3 times by using the accelerator pedal. OK Oxygen sensor output voltage Alternates from 0.40 V or less to 0.50 V or more. Check that each connector is properly connected.

Check the output voltage of heated oxygen sensor during idling

Warm up the oxygen sensor the engine at 2,500 rpm for approx. 90 sec. CHECK Use the OBD II scan tool or TOYOTA hand-held tester read the output voltage of the heated oxygen sensor Alternates repeatedly between less than 0.4 V and more than 0.55 V (See the following table).
