Check for a vacuum leak.

make sure you have the TPS on right and recheck voltage before anything else. also verify the sensor ground wire is a good ground. you might also rotate the TPS with a flathead to see what reading you get when you turn it manually

see attached for correct installation, might be a really simple fix.

also if you read a bit on here you'll see aftermarket cam sensors are JUNK. some last a day, some last a week. its HIGHLY likely that the one you bought is bad already if it didnt come from the dealer

it got 12volts going into the plug, 4.5 volts going to the sensor,.69 volts at throttle when closed only goes to 3.69 volts wide open, when manually opened, book shows should be 4.5 volts, the old one and 2 aftermarket all read 3.69 full open, saw somewhere someone had these issues it was ECM module, there are no vacuum leaks.

Default Re: engine code P2074,,(Oil smoke exhaust)

Hey every one,,
Newbie to the PT Cruiser world.
I just picked up a 2006 convertible with the 2.4 Turbo engine.,
After doing a new owner maintenance checks.
Took it for a ride an found out it started ,idled, and ran great till I tried to step down on it.
3500 r.p.m. it bucked and skipped and the check engine light came on.
Went and got it checked and came back P2074 as you know MAP sensor.
Went to fuel up an the the blue/oil smoke came out the tail pipe.

Tried to get home,,it got worse NO power..
Is the turbo gone an are the TWO related to one another???

THANKS
Any Help Is A Help
