If there is not the same amount of wires it will not work. I can tell you from past experience they may be cheaper but it will cost you in the long run. Do yourself a favor and get the correct O2 sensor for your car. You don't have to get the O.E. sensor from the dealer, you should be able to find a reasonably priced aftermarket sensor that will plug right in.

I think the 2004 Accent only came with a 1.6 liter engine as far as I know. In any case below is as much information I have as far as your code including a wiring diagram of that circuit (CMP sensor). The wiring diagram doesn't tell the wire colors but does tell you where the wire goes or what "pin" number it is at the connectors. I included the connectors which is by number and marked the ECM connector for you. I had a picture of the CMP sensor location but not the ECM location but can tell you the ECM connector is located behind the dash fuse panel. Hope this helps....

2004 Chevrolet Aveo replacing the oxygen sensor's need to know how long the wires are both front and back to order a less expensive brand they have different lengths.

You do not order anything

You DO NOT BUY a universal O2 Sensor

You go to NAPA Etc & buy the OEM Correct
Sensor,with the right length wires & just install it.

You don't replace the rear monitor or back sensors,
just the front ones,closest to the engine & only at
100,000 miles or when they fail

You should be testing any sensor before you replace one.

If you got a Code ,that doesn't mean you replace a sensor

I have a trailblazer 2004. I took it to autozone and the print out stated bank 1 o2 heater sensor with a code of 0141. what do I need to replace? Need assistance

This is the sensor downstream, near the transmission. This is the more difficult of the two only because of the location of the wiring. It's wired into a plug near the top of the tranny, but not too bad. The one upstream, in the engine compartment is in plain view when leaning over the passenger side fender. You can rent a special 02 sensor socket, has a slot on the side of it for the wiring. Other than that, their both pretty straight forward. Don't forget to put a small amount of anti-size for future work.

P0431 code on audi allroad 02

Typcally caused by one of the front oxygen sensors or a bad ground associated with these sensors.Replace both front sensors with direct fit type NOT universal, because there may be a cracked wire and the universal sensor does not contain the complete wire harness. Direct fits, are about $20 more than universal fit type.

The O2 sensors have integrated heating elements that bring them up to the proper operating temperature. Code P0431 indicates that the O2 sensor on your driver side catalytic converter is not reaching the proper operating range. The O2 sensors are usually in the $150 range online.
