This problems has been plaguing me. Got this MAF sensor and replaced relays associated with MAF sensor and I still get code 33... I've reset the computer by disconnecting the battery and I've tried to test the TPS unsuccessfully with a multimeter (stuck probes in but got no reading, might have done it wrong). It could be my TPS but I somewhat doubt it as I've not adjusted it ever. Did any of you have a similar problem? What were your expiriences with this???

 

well everyone here knows the trouble ive had with them(any MAF sensor)...ive had brand names & off names & everything in between! nothing worked,took the car to different mechanics around town & they are replaced the MAF sensor with a new one,leaving me to replace them EVERY YEAR

this last mechanic i took it to,i HOPE fixed it cuz ive had no problems with it i cant remember whats in there now-lol...if you really wanna know i can look tomarrow & let you know,let me know...good luck with yours!!

 

Please do... Other than replacing the relays and the MAF sensor, what have you do in regard to this problem?

 

Anyone?

 

its an "AC MAF sensor" in there now

i dont think they replaced the relays...all of them replaced the other one with a new MAF sensor,thats all they done

 

I know more than 1 person uses the Wells unit... please speak up your input is very important to me. Is there anyone out that that uses the Wells unit that -DOESN'T- get an SES code?

 

When a repair shop gets a code 33 and they replace the MAF. That is not always the case, the relays on the firewall are most likely the problem. Been using the WELLS Maf for two years now without a problem. So if you want to spend $500 for a stock replacement go ahead. But in most cases itis the relays. Also how does the car run if you are getting a code 33 with a WELLS???

 

It doesn't run like it's supposed to. And I have already replaced the relays too.

 

I have the Wells unit and have had no problems with it. Have you tried it in someone elses car?

 

I have no friends with thirdgens. I have a buddy with a 4th and a buddy with a c4. Everyone else is useless

 

Go to the regional boards and try to find someone near you who will test it for you. If you have replaced the relays and still no joy, it may be a faulty unit. I have heard of very few people having problems with the Wells unit.
