tps question please read

Post by **Turb0wned** » Fri Dec 09, 2005 4:35 pm

ok my sr throttle body got messed up in my last car (s13) in the car crash, i put a ka24de throttle body on it, would a 95 tps work if i solder the plug to match? im running a 95 tps right now but it came out of an automatic ka and im having some problems, everytime i get to a stop the car drops to idle perfect but when i hit the gas it turns off, im thinking/hoping its the tps. ive tried 2 different 300zx MAF's and nothing changed. Manual and Auto tps are different right? If u have any idea's what else it might be let me know.

by the way just in case u need any of the information i now have an s14 (1995) with my redtop that was running perfect before (only thing that really changed besides the ecu was the tps and throttle body) a GT2871R, enthapy tuned ecu, 650cc injectors, 300zx MAF, and i havent put my walbro fuel pump in this car yet so im on the stock pump.

wow, stock fuel pump. i'd be a lot more worried about that than anything else.

anyways, talk to a good 240 shop and get a RWD SR's TPS. i tried the one for USDM FWD SR's; actually, i cross-referenced the OEM's ID number on the back of it and traced it to some obscure USDM car, and bought the TPS, and depinned the connector and repinned it to the original connector that came from my swap. the car wouldn't rev over 2000rpm. so in short, just get a used one from enjuku or something. it should be about $50.

KA TPS's should read differently. You can use the TPS off of a B13 or B14 Sentra. It is a crossover part. Manual TPS's should have 3 wires, Auto TPS's should have 6. Also remember that when you put a TPS on its not simply a matter of bolting it in place, you need to make sure its exactly in the right place, adjust it and drive around. The slightest adjustments can make the car run totally different.

i know the SE-R part is supposed to cross over, but i bought a new one and adjusted it and it read perfectly with the ignition in position 2. then when i drove it it wouldn't rev over 2000rpm. i unplugged it on the side of the road and drove the car home. the car worked perfectly w/o it. BTW i have an automatic harness and TPS, so for manual cars this may be different. i did get the proper 6-wire TPS though and it still didn't work. the solution was that one of the guys at XAT hordes automatics SR TPS's and was nice enough to give me one. i love you guys . . .

I have an Auto harness too. The 6 wire TPS needs to be redone so that the white wire, black wire, and green +red wires are the only ones left.

If you use an auto ECU then you can run without the TPS. I ran without a TPS with an auto for a couple years. Then when I went to a manual ECU I needed to tune the TPS.

well on my auto TPS it has 4 white wires (and 1 black and 1 red) i believe. hence the dilemma. i run a MANUAL ECU, BTW. i always have. and it ran fine w/o the TPS for a couple months until i picked one up at XAT. it didn't do much for the car, but i'm happy knowing it's a non-issue.

ok but im running a ka throttle body? would the tps off my broken sr throttle body work?

Post by **95lstegman** » Mon Dec 12, 2005 7:10 am

yes it should. the ECU is looking for the SR's TPS responses. and since most nissan TPS's are the same on the outside, it should bolt up. good luck

Post by **Turb0wned** » Mon Dec 12, 2005 6:43 pm

a sr tps will not bolt up to my ka thorttle body, one is external (sr) and one is internal (ka)

i think i might have found my problem i tried running the car with the MAF disconnted and the car ran without shutting off on me ofcourse it wouldnt rev passed 2k with it disconnected but it didnt shut off on me and it ran, would this make sense to anyone else? should be MAF right?

Post by **95lstegman** » Mon Dec 12, 2005 6:52 pm

i have a burnt ECU that i soldering in a new wire where it got burned and now it idles at 2000rpm and won't shut off. if yours is a MAF problem then i need to track down the circuits for the MAF inputs. perhaps they are in the lower right hand corner where the main power supply fried itself?

I'm having a problem with my SR and I was entertaining the thought of bad TPS... Took it for a drive today and power was very random... maintaining throttle it bucked and spit a lot, and would not even try to idle. brought it in to double check the timing, unplugged the tps and it idled like a champ. Plugged it back in and it died. That's about as far as I got. unplugged, the idle would die if I flicked it and let it come back down. Could be a MAF issue too but the idle was rock steady and very smooth with the tps unplugged...

sorry for the jack

yup, good old TPS problem. with my bad TPS that 100% didn't work, it was okay, but with the new one i cross-referenced that apparently wasn't exactly the same, and that's how it drove, except it woudln't rev over 2000rpm as well. no MAFS problem, just TPS = junk.

parts guide says 97 se-r tps will work.

this thing look right?

Post by **95lstegman** » Thu Dec 15, 2005 10:14 am

that's what i tried, and as i said, it ran WAY worse with it. i thought the guy said '98, but something like that.

Post by **Turb0wned** » Fri Dec 16, 2005 5:09 am

my problem is this...if i keep the idle above 1k at idle when i press the gas it wont die on me... if the idle goes under 1k when i press the gas it will turn off. ive tried 3 different MAF already and its the same thing. about the 97 tps it worked fine for me before but like i said in the accident my throttle body broke so i have a ka throttle body which uses an internal TPS while the sr20det uses an external TPS. basicly theres no way i can put the TPS i used before on a ka throttle body.

ummm, hate to state the obvious, but . . . why not get an SR throttle body? i think enjuku sells them for $40 w/o TPS, then get a TPS from autozone if that worked for you.

Post by **Turb0wned** » Fri Dec 16, 2005 8:06 am

$40 really? im gonna check that out right now

Post by **95lstegman** » Fri Dec 16, 2005 10:47 am

yeah i just checked it out. they sell it for $44 now, but the TPS is $99 from them, so yeah, don't get that from them. i love the guys over at Enjuku though. they're all hella nice and all. i definitely recommend them to anybody looking for service/recommendations/etc. A+ SR shop.

Post by **Turb0wned** » Fri Dec 16, 2005 7:35 pm

yea i bought something from them before, i guess ill just end up buying the throttle body from them and use the tps i was always using, thanks

Post by **Neil** » Tue Dec 20, 2005 4:05 pm

So what's the difference between B13 and B14 TPS's? cuz i just read on the SR20Forums that when swapping in a bluebird you want any B13 chassis SER tps. It's probably got something to do with how the linkage interacts with the tb but I dunno. As long as it reads between .45 and 4 volts from closed to wot it shouldnt matter, right? unless they repinned the plug on a B14 chassis sr
