P0108 need help asap!!!

so i was on my way to work earlier this week and getting on the freeway my engine lost power. it was still pumping fuel but no spark. i had it towed home and replaced the distributor, coil, wires, and map sensor thinking they would be fast and easy fixes without any success. the engine cranks and pumps fuel but i get no spark. im running out of time and money to fix. i pulled code p0108 which is map/baro circuit high input.

i have seen many other people who have gotten this code and they all say that i need to compare readings while the engine is running, but my engine does not start.

Here you go, hope this gives you a start on Where to look bro.

Fault Code Definition

The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold.Thisprovidescritical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems.The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold airpressure into a voltagethatishigh when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.

Common Problems That Trigger the P0108 Code

Manifold Absolute Pressure Sensor/Barometric Pressure Sensoris defective Intake Manifold vacuum leaks Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

Try taking the handle of a screwdriver and giving the MAP sensor a few whacks, not too hard, but with a little force.

Re: P0108 need help asap!!!

So I installed a brand new exhaust manifold (OEM Headers and OEM Catalytic converter) and the shop also changed the bottom O2 sensor and I still have the CEL.... Wow, i'm $800 into this piece of crap and i'm leaning towards giving up. I guess i'm gonna check the wiring of the MAP sensor. Does an aftermarket intake have anything to do with this? All my vacuum lines were good. Please someone help me ASAP thanks.

i replaced the map sensor so i dont think whacking the new one will help lol vacuum is ok so it must be wiring. gotta find the short, that is the only thing that would make it stop running completely so i guess i should have started there. just not looking forward to it.

check the MAP sensor connector pins, they may be corroded causing a faulty connenction

Re: P0108 need help asap!!!

figured it out. the timing belt jumped. which had been replaced 2 weeks ago by a mechanic 3 hours away via the previous owner. i will be sending the shop that originally did the **** work the bill for the timing belt work and more likely than not the valves will be bent also so they will be getting a bill from that and a letter from bar.
