Looking for some direction with the 07 V6 Stock 5 sp Pony with 175K on it.

Car is running greAT, no changes, noticed the Check Engine light was on this morning, took it by Autozone and the code that popped up was P0108.

It shows its for the Manifold Absolute Pressure / BARO Sensor High Input.

Can anyone shed some light if there is something I can do to reset light or if its something it has to go to the shop for.

I see reference to a EGR (Exhaust Gas Recirculation) Valve, with failure causing increase emissions, does that need replacing, if so, any diagrams showing location in engine bay? Is it a DIY? Not sure if its like older PCV and glogs.

Thanks for any help and direction.

p0108 is map sensor pressure circuit high

otential causes of a P0108 code:
Bad MAP sensor
Leak in vacuum supply line to MAP sensor
Engine vacuum leak
Short on signal wire to PCM
Short on reference voltage wire from PCM
Open in ground circuit to MAP
Worn engine causing low vacuum

make sure that all vacuum hoses are connected, and there are no leaks, check the harness to the sensor for rub throughs or damage to the wires. if that checks out, replace the sensor, clear codes, and retest.

Thx for the info, any chance you have a diagram showing location of sensor?

Something I can look for at local Autozone/Advance or is it better priced on web?

the map sensor should be bolted to the intake manifold, not sure about pricing, check around
