Pontiac Firebird Code P1404 EGR Problem
Question:
Would it be difficult for a fairly skilled auto hobbyist to replace the Exhaust Gas
Recirculation(EGR) valve that is tripping the OBDII P1404 code, or would I be better off taking it
somewhere to get it fixed, my problem is that I am a full time college student working part time, and
my budget next to nothing, because I have no help from anyone. Thank you so much for any
response you can offer. Pontiac Firebird 1998 3.8L V6 service engine soon.
Answer:
See picture below. Yes, if you have some mechanical knowledge, you should be able to perform this
replacement. Just remove the 2 bolts and the valve comes off. Be sure to replace the gasket under it.
Note: that code has also been related to carbon in the valve making it stick. You may want to remove it,
tap in on the floor and see if a bunch of carbon comes out. Also use a small screwdriver and make sure
that the valve pintle/pintles are not stuck. They should be able to be pushed into the valve easily. If not, that is your code P1404.
Question:
Pontiac Firebird. V6 3.8 check engine light. Computer codes: bank 1 sensor 3 I had the codes ran for check engine light and the mechanic told me it was
BANK ONE SENSOR 3. I dont know the location.
Answer:
You're talking about the heated oxygen sensors on your vehicle. Bank 1 is the
left bank of the engine, and Bank 2 is the right side. When you have a Bank 1 Sensor 3
code, it is always the furthest oxygen sensor from the engine, usually right past the
catalytic converter. Since both banks go into a single pipe, bank 1 is the continuation of
the series. So you need to replace the oxygen sensor past the back side of the catalytic
converter.
