Question about 2003 Toyota Tundra
No throttle response during cold weather 10 degrees or colder only. It is hard to start and I have to push pedal all the way to floor to get vehicle to move and it will shift extremely hard when I put it into gear. This happens only during first startup. After I warm the engine up I have to shut engine off then restart and throttle works again. What is problem? sounds like a cold weather sensor but what part would I need to replace?
This throttle body has a TPS ( throttle position sensor) and a Accelerator pedal sensor on it. The TPS is on the drivers side and the APS is on the pass side of the throttle body. When this happened your check engine lite came on then went off when it warmed up and acted normally. The code is still in History codes. Check it with a scan tool. I foget the code number but if it come up with the APS code in History, replace that sensor....not the TPS. It is a sealed sensor that gets moisture in it when the seal deteriates and it freezes in very cold weather.
