I have a saturn sc2 (2002)and the service engine soon light came on, took it to mechanic and it showed codes p0133, p0326, p1599, and p1601.Mechanic tested all related components and they tested good. So he reset system. two days later the service light "wrench" and security light came on, I turned the car off, and they went out. The next day the service engine soon light came back on...the car has recently had a motor from a newer model saturn put in it, could this be part of the problem??
Need a different mechanic
They never tested anything,
if you got codes
Testimonial: "They wre the ones who got the codes. Quite sure they tested the related components, the car runs and drives fine. Why would they not test anything if their work is guaranteed and I can bring it back to be re tested for free (unless they have a lot of time to waste) I'm just looking for clues as to what it might be"
They were the ones who got the codes and I'm quite sure they tested the related components. Anyone who could give me a clue as to what the problem might be would be appreciated
Google the codes Type: OBD PO 133 etc If you had codes them there was not only component testing to do but why wasn't the cause of those codes found & resolved They did nothing to resolve why Was the car road tested & did you go along for the ride Have to do that

Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

It seems that you have a loose wire, bad connector or perhaps the main computer itself that is causing a problem If the shop is not seeing any codes, or codes come and go, likely I'm right...but someone is going to have to actually do some intensive testing to find the real cause. You can likely get another computer from a local scrapyard far cheaper than what the dealer will charge you...as far as wiring, you need a good accurate schematic a good volt/ohmeter and lots of time to trace wiring. When checking connectors test the pin, then probe the wire going into the pin...often the problem is where a wire meets the backside of the pin, either corroding or breaking..This also applies to any modules such as the security system...what you see on the dash does not always tell you that connection to components is good. This is not a "fix, but rather, a direction to go in. (exactly what I"d need to do if I was there)
Right now, everything is suspect including fuel system, till you rule it out!!!

It may be a shift solenoid or a speed sensor look up the codes online google your cars year, make ,and model and be sure the fluid is not too low, check the fluid level warm while the motor is running.
