Everyday this "check engine light" comes on with those errors. I have a OBDII Scanner that checks this. I did find a tube located on the right side of the Air intake plenum housing and it goes back to the engine body. The tube is about a 1/2" a round and it gets oil on it. If also checked: I have new air filter, just had an oil change service, and found no looose connection except the the one I just discribe above. Any help is appreciated.

P0174 - System Too Lean - Bank No. 2.
P1152 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 2.

The above two would indicate that your O2 sensor is going bad, has failed or you have a bad wire running to it. But can be associated codes from the one below.

P1537 AND P1538 - Intake Manifold Runner Control Stuck Open.

You might want to look at the imcr valve. It is probably sticking from carbon build up? Use top engine cleaner and clean the air plenum.

Once you have done this clear the codes and go for a ride. About 30 miles should do it. If you have anymore codes it will come back up.

If the 02 sensor codes come up again you will most likely have to replace the o2 sensor. But clean your imcr valve first.


Regarding the P0717 I dont have anything on this one. Did you mean 171?

Probably, one of your IMRC has gone bad (from the codes, P0174, P1537 and P1538). You will need to replace it.

P0717 - Input/Turbine Spped Sensor Circuit No Signal.
I don't know what it is...
