Doesn't idle, hesitated, codes 14,21,45,53

[fixkick]

you paid $200 for a new TPS.,??? i hope not.
the ecu checks each sensor, constantly, key on and running,
un ending, and some take driving hard to get. set. (Failed)
so when it says 45s, that does not mean a sensor is bad.
only that it reads wrong, and that is wires bad,
its just 3 parts here.
ECU
wires
sensor. (that most be calibrated after removal)

if set too loose (gap) the engine will hesitate
if too tight, the engine will not have idle controls.
it has to be calibrated to work right. on all 89 to 1998 suz.


the code you have now, means the idle switch pin is not calibrated, did you just swap it in and not calibrate it?
when the engine is at idle. the switch is closed. and at 0 volts.
if not zero volts,the ECU complains, and can not control idle. , like that.

you can not just throw on a TPS.
pull the dome fuse to reset all DTC errors. is the best way.
also if you pull sensors wires, with the key on , it will store all those errors. so dont do that or use the DOME fuse to erase them...
here is the TPS calibration.
