Replaced 0xygen sensor in 2001 Accent L. Check engine light is still on. What to do?
I have a 2001 Hyundai Accent L with a 16 DOHC 4 cylinder engine. My check engine light came on a few months ago and I had the codes read. The codes were p0030 and p0133. They came up as being a possible bad oxygen sensor (front position before the catalytic converter) or a bad electrical connection. I purchased a Bosch OE Type sensor from auto zone, put it in, disconnect the battery to reset the check engine light, but after driving the car for 100 miles the light came back on. I had the codes read and the same codes came up. I took the O2 sensor back to auto zone and asked for a new one. They gave me a new Bosch OE type sensor and I installed it, but the light came on again. So I order an Hyundai OEM Factory Oxygen Sensor, installed it, and the same story. The check engine light came back on. In order to beat a dead horse i figured I would try a universal sensor. I bought a Denso 4 wire O2 sensor, installed it, cleaned and put electrical grease on the connections, but I am still getting the same codes. What in the world could possibly be wrong with my car. I took it to a ASE mechanic and he told me that my oxygen sensor was bad. I told him I already replaced it and he said that he would have to start by replacing it again and then figuring it from there. I have to pass emissions in 1 month. P.S. I also replaced my 2nd bank oxygen sensor with a factory OEM sensor from Hyundai. Any help or advice would be greatly appreciated!

Look for an exhaust leak... 99% of time we find crack at accordion for the front pipe.
Get it to where you can get ear close to it and listen, or feel for stream of hot exhaust gas coming out. Maybe exhaust manifold crack, but that we do not see with Accent. |

Fuel filter is usually located under the back seat...there is the fuel tank, fuel pump and the filter...Also check the vapor canister and the canister valve...they might be blocked...if the canister is not good it will send charcoal up and that's when it blocks the canister valve...Hope it helps..
