瀚慖f the test lamp does not illuminate, or flash, test the control circuit for a short to voltage, or an open/high resistance. If the
circuit/connections test normal, replace the K20 ECM.
Note:
* Less than 10 ohm on the ignition voltage circuit, or control circuit may set a DTC. If there is resistance on a circuit the driver will remain
ON and the scan tool will display greater than 0.00 amp.
* Performing this test may set additional DTCs.
5. Ignition OFF, connect a 10 A fused jumper wire between the control circuit terminal listed below and the ignition voltage circuit terminal D.
* B52 HO2S 1 terminal E
* B52 HO2S 2 terminal C
6. Engine idling, observe the appropriate B52 HO2S Heater parameter. The scan tool should display 0.00 A.
瀚慖f greater than the specified value, test the control circuit and the ignition voltage circuit for high resistance.
7. If all circuits test normal, test or replace the appropriate B52 HO2S.
