My Truck has been throwing code 22(TPS low voltage). I replaced it last week and it still throws the code intermittently. If the SES light is off then the truck runs great, when it turns on the truck shifts really hard and idle is around 1500 rpm. I have checked the TPS for dead spots and its still good also its new. I also checked all connections and grounds and everything looks good. Any ideas on what else I could look for?? Please let me know. I am so lost with this problem. thanks

look for a break in the tps wiring or corded ground on the water neck

are you talking the TPS as in throtle possion switch or as in temp switch thats right below the thermostat neck

tps the wires go into the loom and they break because the angle i had to re do mine

Be sure your sensor grounds up at the front of the intake are in good shape. If they're corroded, damaged, not hooked up...you'll have some issues.

If you unplug the TPS (with key off) then crank it up, how does it run? Obviously you can't drive it, but how does it idle.
