when i turn the ignition the ingition acc position the comander say's boost for the map sensor reads 1.19 .has anyone had this problem before ? could any one help me with this

 

Have you observed boost as you drove?

 

The map sensor is on the wrong setting, the sensor is faulty or there is a wiring issue. It should not be reading boost.

 

also the pfc pim is readings 100% all the way down!
i have checked out the map sesor and it is good .
bonzai.. would you know where in the wiring should i start to check for bad wiring.
thank you guys for any input.

 

any one else have any clues?

 

I just recently had this same problem. Check the power running across the connector for your map sensor. Ohm out the ground which is the center pin in the connector. If the ground is bad, just cut it and put a ring connector on it and re-ground it. If thats good, check the 5v to the ground in the connector. If thats good, it is most likely a bad return line.

If you still have your stock ECU, put connectors on the cut lines and put it back in. Then pull fault codes with your check engine light. The factory manual has the proper pins to jumper to read the light.

 

There are only 3 wires that go to the map sensor, take a look at the FSM, it is really easy to trace them down.

 

ok guys update ....not i but we fixed it ! special thanks to kevin landers,bonzai racing and forienracer. the problem was a bad ground on the map sensor wire again thank you everyone!!!!!!
