Brand New tps Still same problem?????

[Sleeper415]

Was up guys. I got a sr20det and I thought my TPS was bad sence it was plugged in my car it would read my throttle really wierd. I unplugged it because I thought it was bad so I got a new one and same problem.

When I give it gas it wont respond right away, then it jumps and act's really funny. Need help thanks.

When I had it unplugged and it was getting the signal from my MAS its fine i just cant drop it in nutral at high rpm's because my rpm's drop to 0 do to the TPS not being plugged in. Correct me if im wrong thanks.

hey man

hey man what engine do you have, i know on mine (97 blacktiop s13) i needed to use an s14 tps, it took like 2 monhts of talking wiht the guys at phase2, it was weird like they had never had someone else need a tps but anyways after sending me 3 new s13 ones they finally sent me an s14 onme which works great , itd help if i knew what enigne u have but thats about all i know too. hope this help

[Sleeper415]

Iv got an SR20det redtop not to sure what year but thats what I got. Thanks

O before I forget the TPS I got is off a 91 sentra se-R fits, pluges in and everything I really dont know whats wrong.

so your having really bad missing and hesitation? are you running rich at all? do us a favor just check the tps voltage anyways with a voltmeter..readings should be .45volts to .55volts and idle and 4.5volts at w.o.t. If that all checks out then check your maf voltage. you should get a 12v reading, 5v reading and the other is a ground..if that works out then clean your maf with electronic cleaner out of a spray can. if nothing still then get back to us

[Sleeper415]

ok ima try everything out and get back to u guys thanks

[Sleeper415]

Double checking to make sure im doing everything correctly. I taped into the light green/red wire, thats the one I was using to check my volt's. Then I fliped the key to ACC and checked it. 5.18???? I also turned my car one and checked it, I got 5.16??? is this right ?? Am I doing it wrong?? The volt metter is set to 20v.

[S13FASTBACKSR]

no thats not right..thats reading at w.o.t. when the engine is really at idle..set the volt meter to 2volts but i dont think it will change much..for the most part it sounds like you need to adjust your tps

[Sleeper415]

Do you mean move the TPS around see if my voltage changes? If so I just tryed it and nothing happened. Could it be my wireing???

[S13FASTBACKSR]

ya loosen the two bolts and move it up and down. the voltage should change because its a brand new tps..also i dont think its the wiring because the green wire with a red stripe is your power wire and you got a power reading from that and plus did you even mess with your wiring? or just plug it straight in? when did you start having this problem..as soon as you started the engine right after the swap?

[Sleeper415]

Ya I had to rewire the whole pin when I got my motor the blue pin was in 3 peaces. Im really thinking thats my problem, I want to cut the wires from my the TPS. Then run 3 other wires from the TPS striaght to my ECU????

[Sleeper415]

Ok I ran the TPS input wire to the ECU and nothing happened my voltage stayed the same. I checked the black wire witch I beleave is my ground, still good. I dont know anymore im out of ideas, I starting to think I got a bad ECU???? But if I do why is my car running when my TPS is not plugged in ????

Sorry for all the questions just want my car to be running like it should, and I really so appreaccate the help.

[S13FASTBACKSR]

bro why the hell was that connector broken into three pieces? how did you get the pieces back together? its a huge possibility that your connector isnt making connections to the ecu's pins when you bolt it down because of how you possibly rigged it back together.

[Sleeper415]

One of my friends wired it up for me. I mean it started up one the first try but I don't remember if I had the problem right away or if it came right after. I never did anything about it because I never had the money to buy another TPS. I finally got one but im still stuck???

Well it was a big a*s mess.

1 That pin was in three peaces. 2 I had the wrong ECU3 My oil pan was bent in from the bottom4 My turbo didn't have the coolant lines on it5 My elbow from my turbo that goes to the down pipe, the scrwes were broken.

Every things ok now except for the TPS and its driving me crazy.

[S13FASTBACKSR]

lol so you dont know if you had these problems the first turn of the key after the swap? it just doesnt seem that you could take three broken pieces and glue them together or whatever you did and make them have a good connection..if you had these problems right away i'd say get a new connector and make sure you wired it right. but your tps voltage doesnt change at all even when you adjust it? Do me a favor..go turn your key to the on position and look at the l.e.d. on the back of your ecu..it should be on..now start your engine..the l.e.d. should go off..if it doesnt then your ecu is bad..go check that and also if it does go off check for codes and let us know what you get

[Sleeper415]

For the LED light to come on do I have to even tuch the Mode Selector at all??

[S13FASTBACKSR]

no it should just come on when you turn the key to the "on" position (engine off) is it not coming on?

[Sleeper415]

Ya I think its my ecu I turn the key on and no the red led light never comes on?????

[S13FASTBACKSR]

ok..well do you know how to check your ecu for codes? if not this is how you do it...

....with the engine off turn the screw on the back of the ecu fully clockwise and hold it there for 2 full seconds. Then turn it back fully counterclockwise and it should start to blink a series of flashes. short flashes then fast..3 short (slow) flashes equals the number 3. and say 4 long (fast) equals the number 4..that would be a code 34. let us know what you get

[Sleeper415]

Ok the mode screw was in the clock wise thats why my led light wasnt turning on. I turned the key off put it back to counter clock wise, turned the key on, and then back to clock wise for 2 sec, back to counter clock wise and it throughs the code 55??????

Is my ecu still bad???

[S13FASTBACKSR]

lol wait..so now when your key is on your l.e.d. comes on correct? ok now start your engine, does the l.e.d. go off or stay on? also are you checking for codes with the engine running or not running? I believe you are doing it not running. Try running now

[Sleeper415]

ok I turned it on and I tryed to read it but nothing happend (no light). I dont run it with the TPS plugged in so i plugged it in before I turned it on. But still nothing, I took it around the block, came back, turned it off, I checked for codes and its giving me 34, and 43????

[S13FASTBACKSR]

34 is knock sensor and 43 is tps..zerothread?id=32578 I know this is getting annoying but now try with the key on not the engine running

[Sleeper415]

Same. i turn the car on and i can't get a reading then I turn it of and it reads 34,43.

[S13FASTBACKSR]

ok bro we are gonna figure out if its the tps once and for all...

.....we are going to check the power supply...unhook the TPS and then turn the key "on"...now check voltage between light green with red stripe wire and a ground. voltage should be approx. 5v.

....if that works out fine then we are now going to check your ground circuit. turn ignition switch back off..make sure your ground screws are nice and tight. check continuity between the ground terminal and a ground.

....if that works out ok then next we will check input signal. with key on and tps unplugged check voltage between terminal b and a ground. you should get between .35v to .65v at closed throttle at then if you push the lever fully open you should get 4v.

....if that works out then we are next going to check continuity between the ecu pin and tps "B" terminal. disconnect both ecu plug (the blue one and put it on the tps pin 20 for a redtop and the "b" terminal of tps and you should have continuity.

bro did you ever do what i last posted? i just wanted to pass by you that when the key is in the "ON" position you got the right voltage..but the engine running you didnt..you got w.o.t. so that was wrong..if you did all the steps i told you in my last post and everything checked out then i think it may come down to your ecu
