Traction control light /loss of power
 

So about 5 weeks ago this problem started... I'm driving around 30 mph and then the tract ion control light comes on and I loose power to the throttle and can't change gears. I turn the car off and back on again and drive off like nothing happened. Over the next couple weeksit happens on and off with no real rhythm to explain it. My local Nissan dealership said they co uldn'tfigure it out. I took the car to R/T tuning in Lansdale PA to get a custom tune and they said it was the tps sensor on my passenger side throttle body which I replaced three days ago and the issue is still there. Someone please help!

saw something that may relate. issue was the ABS cause there wasn't any brake fluid or it was extremely low on fluid. it's easy to check too. good luck

Thank you I'll check it out

Just checked the brake fluid and it's on max. Also saw on another thread to check the brake switch... I dunno hope I can figure this out soon

ABS wires


You said RT Tuning said it was a TPS issue?

Brake switch could do it. If its sticking its not going to let you accelerate.

Correct me if I'm wrong though, the TC light wouldn't illuminate if that was the problem

No I think your right. I only tried to do a brake boosted launch once and found it quickly that it wouldnt work. I dont remember that blinking tho. These issues are truly the worst ones to try and figure out as it gets very expensive replacing parts.

I would check your ABS wheel speeds with a scanner that can see them.

Just checking -- but is VDC off?

Yes R/T tuning said it was throwing a tps code and they checked and sure enough the passenger side throttle body had a tps sensor that was obviously cracked but I've since replaced it and it's still happening.

And to answer vdc questions I don't even know how to turn it on or off so I doubt it's that. Only had the car for about 10 weeks and with all the mods I've done all as soon as I got the car I'm still trying to bond with my new ride

Also at one point the issue was so bad I couldn't drive for 5 min without it happening so I would reflash the ecu with the uprev /Osiris tune that came with the Stillen supercharger kit and everything seemed fine for a couple days then it would start happening again but now I have a custom tune with R/T so I can't reflash

Any check engine lights?

Yes the check engine light is on

the VDC button is on the left side of the dash behind the steering wheel sort of. you won't be able to launch without turning if off after you start the car. you have a lot of power so VDC may be killing your acceleration. i think boosted Z guys either drive with VDC off or get a fancy race logic traction control system. just be careful lol
