oxygen sensor circuit problem may have to do with the electrical wiring for that sensor, replacing the sensor may not solve your problem you have to check that circuit first. As for the second code the low efficiency of the cat is signalling that the cat is on its way out. |

@ atuegbe, Code P0031 means your A/F sensor Bank 1 sensor 1 has issue ranging from 1.A faulty Air/ Fuel ratio sensor is faulty 2.Bad wiring connection to the sensor circuit 3. An open in the Air/Fuel sensor fuse 4. ECM fault. Most likely is the faulty A/F ratio sensor. It is the precat that is the sensor before the Catalyst on the Manifold End of your Exhaust close to the radiator. For the code P0420 - Catalyst system efficiency below threshold It is a fault that denotes the present of Catalyst or not. A quick check is having a panel beater confirm the presence of the CAT. or the State it might be in deteriorating condition. The CATALYST deteriorates with age. If so, replacing the CAT is a good option For further help Contact : 08061183339 |
