Problem with my 2004 GMC ENVOY
Year = 2004
Mileage = 39,000
Engine size 4.2 l straight 6
dash lights = SERVICE ENGINE SOON
GM trouble codes P0410
work done to repair = I HAVE CHANGED THE VALVE SOLENOID CHECK THE FUSE
FOR THE SOLENOID. CHANGED THE AIR PUMP AND THE RELAY FOR THE AIR
PUMP.
BUT THE PUMP STILL DOESN'T TURN ON.
Tech = MW
question = WHAT ELSE IS THERE TO CHANGE TO MAKE THAT AIR PUMP TURN
ON.
I TOOK IT TO SEVERAL MECHANICS AND THEY CANT FIGURE IT OUT. PLEASE
LET
ME KNOW WHAT YOU THINK. (I HAVE CHANGED THE VALVE SOLENOID CHECK
THE
FUSE FOR THE solenoid. CHANGED THE AIR PUMP AND THE RELAY FOR THE AIR
PUMP. BUT THE PUMP STILL DOESN'T TURN ON.
MW:
There is also a fuse for the pump. If that fuse is ok, then the next thing to check for
is that
there is power at the pump relay, then ground the relay to turn on the pump. If you
can
manually turn on the pump, then the problem may be with the pcm. The pump relay
ground
is controlled by the pcm. When you say that the pump never comes on, i assume
you are using a scanner that can control the pump. The pcm will only turn on the
pump under certain conditions. A scanner that can control the pump can turn it on
anytime. The p0410 is set
under curtain circumstances, and it monitors the #1 02 sensor to determine if the
system is
functioning properly, and decide to set a code.
