Im picking up an evo tommorow and the dealer told me the O2 sensor needs to be replaced...now is the engine check light going to come on because of its absence?

 

if the o2 is def shot then yea u will have a check engine light

 

If you're buying it from the dealership (or anyone for that matter), tell them to fix it first or subtract the cost from the purchase price. A bad sensor will yield a CEL. My recommended fix would be a universal 4-wire Bosch sensor from the auto parts store for around $50 then just wire it into the stock sensor's harness.

 

Well i dont mind shelling out the money to fix it...i kinda new to this whole evo pandemic lol..but yeah thats all i needed to know ill get it fixed first thing...thx again...

 

I have the universal Bosch and have had no issues. I would definitely make them fix it. I am always suspicious of dealers selling cars saying "it just needs X"or "just replace Y and it will be fine" I dont buy it. It is a lot easier to sell a car without a CEL. If it was something that simple, one would think they would just replace it first, then offer a car with zero issues. I would ask that it be fixed before you take the car. Who knows what the real issue may be.

 

yeah true...ill bring it up to him tomorrow when i pick it up i also got a good deal on a two year warranty if the car has any issues...so wish me luck..

 

Good luck and Hope ya got a deep pocket book. These cars tend to be worse than crack. Once you do one mod....you will find anyway to get the next one.

 

bro, i would not trust that. just like SEEnoEVO said, you dont know what the real issue is, or what caused it. i'd be suspicious about it. GL tho!

 

Well i just got finished paying off a 02' 325i...you wouldnt imagine countless parts ive had to buy to keep that thing running...but yeah thx for the heads up....

 

now if i decide to install a 02 wideband will that be able to solve my missing 02 sensor problem?

 

if u install a wideband u still need ur factory o2 sensors in place u just have to make a hole for the supplied wideband o2 sensor somewhere on ur downpipe

 

i gotcha thxx

 

np bro nd good luck wit the cel

 

I would definently tell the dealer to fix it. Seems like they would anyway. I paid way to much for my evo and the car was pretty much mint with only 2,7500 miles on it. The car had a few scratches on the hood and the dealership was hesitant about fixing them. You would think they would have the courtesy to fix it right away. Just ask em!
