4. Ignition ON, install a 3 A fused jumper wire between the signal circuit terminal B and ground. Verify the appropriate scan tool B52 HO2S
parameter is less than 60 mV.
锟斤拷If greater than the specified range, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the K20 ECM.
5. If all circuits test normal, replace the appropriate B52 HO2S.
