Do we have to replace more that 1 02 sensor for a po130 and po133 codes?

Question

Have replaced the front o2 sensor, fuel cap, spark plugs, trying to pass emissions

Answer 1

Hi there

Both of these codes are for the same O2 sensor. Bank 1 sensor 1. Since you are still getting the codes I would check the wiring from the fuse box and the computer. It could be there is an issue with the wiring.
