Hi all. Well today on the road, I was stop in traffic. So once the traffic is clear I step on the gas and notice something is different. I'm unable to move/rev up/fast. I turn off the main road into a parking lot, I notice the vsa light is on. I put the car in park rev it up and only goes to around 3,000rpm max. I turn off the car, and check the tps sensor at the tb. It's plug in, so I turn on the car, and it rev up like normal. I got a cel code P2138 generic. throttle/pedal position sensor/switch D / E voltage correlation.
I was able to drive like normal back home.
basic info on car
06 tl auto s/c, hbp, hondata flash rsx injectors. recent upgrades aem fic with custom plug and play harness tuned. Any input? do I need to replace the tps sensor or something which might occur again?...
thanks for your inputs...
Michael
