INSPECTION PROCEDURE
1
CHECK DTC
a
Clear DTC (See DTC CHECK/CLEAR )
b
Turn the ignition switch off
c
Disconnect the cable from the negative (-) battery terminal and wait for 1 minute
d
Connect the cable to the negative (-) battery terminal
e
Turn the ignition switch to ON

DTC P0606 ECM/PCM PROCESSOR
DESCRIPTION
The ECM continuously monitors its main and sub CPUs This self-check ensures that the ECM is functioning
properly If outputs from the CPUs are different and deviate from the standard, the ECM will illuminate the
MIL and store a DTC immediately

a. Inspect the P0136, P0137, P0138, P0156, P0157 or P0158 flowchart.

If P0136 or P0156 is output, troubleshoot for that DTC first (See DTC P0136 OXYGEN
SENSOR CIRCUIT MALFUNCTION (BANK 1 SENSOR 2); DTC P0137 OXYGEN
SENSOR CIRCUIT LOW VOLTAGE (BANK 1 SENSOR 2); DTC P0138 OXYGEN
SENSOR CIRCUIT HIGH VOLTAGE (BANK 1 SENSOR 2); DTC P0139 OXYGEN
SENSOR CIRCUIT SLOW RESPONSE (BANK 1 SENSOR 2); DTC P0156 OXYGEN
SENSOR CIRCUIT MALFUNCTION (BANK 2 SENSOR 2); DTC P0157 OXYGEN
SENSOR CIRCUIT LOW VOLTAGE (BANK 2 SENSOR 2); DTC P0158 OXYGEN
SENSOR CIRCUIT HIGH VOLTAGE (BANK 2 SENSOR 2); DTC P0159 OXYGEN
SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 2) ). Then proceed to "6
INSPECT ECM".
If P0137 or P0157 is output, troubleshoot for that DTC first (See DTC P0136 OXYGEN
SENSOR CIRCUIT MALFUNCTION (BANK 1 SENSOR 2); DTC P0137 OXYGEN
SENSOR CIRCUIT LOW VOLTAGE (BANK 1 SENSOR 2); DTC P0138 OXYGEN
SENSOR CIRCUIT HIGH VOLTAGE (BANK 1 SENSOR 2); DTC P0139 OXYGEN
SENSOR CIRCUIT SLOW RESPONSE (BANK 1 SENSOR 2); DTC P0156 OXYGEN
SENSOR CIRCUIT MALFUNCTION (BANK 2 SENSOR 2); DTC P0157 OXYGEN
SENSOR CIRCUIT LOW VOLTAGE (BANK 2 SENSOR 2); DTC P0158 OXYGEN
SENSOR CIRCUIT HIGH VOLTAGE (BANK 2 SENSOR 2); DTC P0159 OXYGEN
SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 2) ). Then proceed to "6
INSPECT ECM".
If P0138 or P0158 is output, troubleshoot for that DTC first (See DTC P0136 OXYGEN
SENSOR CIRCUIT MALFUNCTION (BANK 1 SENSOR 2); DTC P0137 OXYGEN
SENSOR CIRCUIT LOW VOLTAGE (BANK 1 SENSOR 2); DTC P0138 OXYGEN
SENSOR CIRCUIT HIGH VOLTAGE (BANK 1 SENSOR 2); DTC P0139 OXYGEN
SENSOR CIRCUIT SLOW RESPONSE (BANK 1 SENSOR 2); DTC P0156 OXYGEN
SENSOR CIRCUIT MALFUNCTION (BANK 2 SENSOR 2); DTC P0157 OXYGEN
SENSOR CIRCUIT LOW VOLTAGE (BANK 2 SENSOR 2); DTC P0158 OXYGEN
SENSOR CIRCUIT HIGH VOLTAGE (BANK 2 SENSOR 2); DTC P0159 OXYGEN
SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 2) ). Then proceed to "6
INSPECT ECM".
If DTC P0607 and P0136, P0137, P0138, P0156, P0157 or P0158 are output, the output
voltage of the heated oxygen sensor may remain close to 0 V or become high (around 1 V or
more).
NEXT: Go to step 6
3. CHECK FOR EXHAUST GAS LEAK
a. Allow the engine to idle and rev the engine.
b. Check for exhaust gas leaks around the heated oxygen sensor.
If any exhaust gas leaks are present, repair it and proceed to "4 PERFORM CONFIRMATION
DRIVING PATTERN". If no exhaust gas leaks are present proceed to "4 PERFORM
