Vehicle make/model = 1997 oldsmobile aurora
Year = 1997
Mileage = 99000
Engine size = 4.0
dash lights = service engine soon
codes = P1645
work done prior = they change a fuel line as a part of a company recall
and I changed the 2 quick disconect parts where tha nylon fuel line
meets the metal line.
tech = jk
question = I read that p1645 is related to the evap system. when I
drive sometimes the light turns of and after a while it turns off again.
I'm not sure but it looks like it comes on when the car is running but
not moving. or maybe it happened that way just accidentally.can I fix
that by myself? I have to take the car for the emission test soon.
What should I do to fix it?
thank you very much?
JK:
The code you have is for the evap emmisions purge solenoid control circuit. With the repairs made
previously to the fuel system, it is very possible that a wire or connector was pulled off, or damaged.
First, check ALL fuses, underhood fuses, dash fuses, and fuses under rear seat.
Next, remove the engine cover and look for any sensors, control valves in the area of the fuel rail
that may have been left unplugged. Also check for any damaged vacuum hoses. I would bet that is
where you will find the problem, somwhwere around the fuel rail and lines.
