Default Replacing an O2 Sensor without the Dealership.

I have the dreaded “Engine System Service Urgent” message and have been following the threads related to this problem. Since cleaning the Mass Air Flow sensor has failed to correct the problem, I think a new O2 sensor may be in order. From the threads I've read, I can expectexpect to pay around US $800.00 to have the dealership replace this device. Through this forum I have located a website (www.oxygensensorwholesale.com) that sells aftermarket O2 sensors for less than US $80.00. So I assume that the dealership is making a huge profit replacing these sensors.


My question then is a simple one… if I were to order a O2 sensor from the website previously mentioned, how hard would it be to replace the sensor myself? Is this something that really requires the dealership (and it associated mark up)?

have you pulled codes yet? i would go to autozone or advance auto and pull codes before guessing that it is an o2 sensor. have them scan it and then see which codes you have to work with.

oh, and by the way, most of the time aftermarket o2 sensors for that price do not come with an oem style connector, so you have to cut the connector off your old sensor and splice the ends of the new one to it..if your savy with a wiring diagram and a crimp tool id say go for it..otherwise youll hook up a heater circuit wire to the ecu signal or something.. so be careful..

Don't just start throwing parts into your car. Get the codes checked and verify all the specs to ensure you are only replacing what needs to be replaced.

Thanks for the advice, but already got the code: P1133 O2 Sensor Front, Bank 1. I also got a quote of nearly $1000.00 to have it replaced ($419 for the senor and $222 for a sensor mounting bracket) the rest is labor. Seem pricey when you consider that I can get a replacement sensor for as low as $44.00, which is why I was asking whether I should pay the dealer's markup or attempt to replace it myself.
