PT Cruiser Error Code

mercredi 24 juin 2015

Hello AMHD!!

I own a 2003 Chrysler PT Cruiser. It is the GT model with the 2.4L Turbo engine. Lets get right down to it...

When I run the codes I get P1105 (Secondary vacuum sensor circuit).

No other codes pop up, the check engine light stays on, the car runs normal for the most part. There is an occasional shudder and RPM drop when the car is at idle and in gear but stopped. I attribute this to a dirty intake manifold sensor, I cleaned it a while back, will change it soon. No other problems with the vehicle's engine. I got the car at 104k and have put another 40k on it in the last couple of years. I am amazed by the fuel economy for this car. More than a decade old, and well used, a couple of weeks ago from Savannah, GA to Charolette, NC I got 27.5 ish mpg. Even through the mountains north of there I was staying above 20 mpg. It has plenty of power, seldom hesitates and starts in under 2 seconds every time. When I was up north and temperatures were near freezing it still started without hesitation, maybe taking a second or two more.

Anyway, its not the most urgent matter, and I assume it refers to a faulty sensor or a vacuum leak somewhere. All things considered, I have replaced many of the vacuum lines and all of the coolant lines and am working on other rubbers underneath as the Florida weather tends to be harsh on them. How would I identify the Secondary vacuum circuit in order to narrow down the issue? What does that circuit control? Any advise would be greatly appreciated.

Thanks in advanced guys.
