If I clear the code, the engine smooths out and runs correctly
I have removed the throttle body, cleaned it and reinstalled. Problem remains.
The problem remains even after installing another throttle body,
I cleared the codes, recalibrated the throttle body by turning on ignition for 60 seconds(without touching the gas pedal), turning ignition off for at least 10 seconds, then turning the ignition back on, P1502 code reappears
I would really appreciate any advice on how I can get back on the road!
-Is the throttle body the problem?
If not, where should I look?
If the TB is bad, is it OK to try a used one or an aftermarket TB
Thank you

Three possible issues:
Fuel pump relay faulty
Short circuit to B+
DME faulty
Check the fuel pump relay, if bad, replace
If relay OK, check wiring from DME to fuel pump relay for short circuit to B+; if shorted repair wiring harness, if OK you need a new DME.
Good luck...
