hi,welcome to J.A. do you have a multimeter?
here is the circuit on that sensor you will need it to do the test
here is information on
Circuit Description The throttle position (TP) sensor circuit provides a voltage signal that changes relative to throttle blade angle. The signal voltage will vary from below 0.6 volts at closed throttle to about 4.5 volts at wide open throttle (WOT). The TP signal is used by the powertrain control module (PCM) for fuel control and many of the PCM-controlled outputs.Conditions for Setting the DTC
Action Taken When the DTC Sets
Conditions for Clearing the MIL/DTC
Diagnostic Aids Check for the following conditions:
If DTC P0122 cannot be duplicated, the information included in the Failure Records data can be useful in determining vehicle mileage since the DTC was last set. If it is determined that the DTC occurs intermittently, performing the DTC P1122 Diagnostic Chart may isolate the cause of the fault.
Update: I rescanned and now also throwing code P0113 for IAT sensor, which I should mention was just replaced with the TPS sensor. Being that they sharea common ground wire is this where I should be looking? Does this sound like a wiring problem? I will investigate the wiring further in the morning but if anyone could could point me in the right direction or tell me what I should be looking for I'd appreciate it.
then the problem can be the ground. let me see if i can find the wiring on this sensors and get back to you.
New update: I can now add code p1509 to the list after a short drive. PCM?
ok, let me look this up.
ok this is the idle air control valve , does the engine idles low or to hi?
When started it idles low almost to the point of stalling. Depressing gas pedal produces surging however I've found that if I let it "warm up" ie idle for about ten minutes this goes away. I think from I've read that this is because the brain is sending a default signal to set the timing etc.
ok, have you done throttle plate cleaning? if the idle air control is carbonize it will cause this problem
