3 TPS sensors all S4.. 1 is on my turbo 2 and im not sure it's any good. the other 2 are on my S4 N/A engines. (First question).. are all S4 TPS sensors N/A and turbo of the same series calibrated the same and are they compatable? My turbo sensor is reading 6.6 ohms WOT... (2.) shot correct? Thats not the problem if it is shot, the problem is (3.)which N/A (assuming they are compatable with the turbo ecu) would I replace the turbo TPS with? The 1 reads something like.5 OHMs shut and 4.2 WOT and the other reads the same shut but about 5.5 WOT? question (4.) which of the spare N/A TPS's is the best candidate for the job?

 

First of all, yes the original one is shot. Over 6 is bad. Any s4 tps will work, they are the same part number. I personally would use the one that is 4.2k max because it should last longer. 5.5k is on the high side of usable. The .5k low side is lower than it will be when installed because they are slightly depressed even at closed throttle. You will want to adjust it to be in spec once its installed.

 

thanks for your imput. and thanx for geting straight to the point and answering my questions. the tps you sugjested is the one i was assuming was the better of the 2 and tuning it won't be a problem i have some good practice at that now lol

 

np, glad to help.
