Dear MW, i have a
2001 pontiac grand prix check engine light obd2 code p1404 was pulled. Replaced the
EGR valve, but code came back. Any ideas much appreciated.
MW:
If the replacement of the valve did not correct your condition, then you need to have the
computer(pcm) re-programmed with a software update. The update fixes a pintle position
problem that the pcm expects to see, but does not. This must be done with a dealer
scanner. Expect to pay 1 hr. labor for this re-program.
