Had to replace computer in my 2005 PUT Cursier because it stopped shifting and check engine lite was on. Worked one time then check engine lite came back on and would not shift again. Can I reset computer again to make it work?

probly the cable to the computer

You drove with a flashing check engine light and then with it on solid. Flashing check engine light means STOP DRIVING and get it fixed. So this sounds like an abused and neglected car to me. Get the trouble codes read that are stored in the computer. Check for good fuel pressure and spark. Fix one or both.

Check to see if the high speed fan (I think it's the one on the right) comes on when you turn on the air conditioning. If it doesn't, the condenser (in front of the radiator) will overheat and the high pressure switch in the A/C system will turn off the compressor. If this is the case, the fans should be replaced (they come as a set). You shouldn't have to replace the radiator or the condenser if they are not leaking, but have your A/C system checked and serviced if you found that the cooling fans were not working properly.

Hi. Thanks for your question.Before you change trans fluid one more time i would recommend you to visit https://www.reliable-store.com and download the entire workshop manual. It has all the information along with the diagrams for better understanding. Good day!

possable bad brake lite switch. also check fuses.

check fluid level and see if the fluid smells burnt and fluid is black

Take your car to a Toyota dealership. Have them scan the car for trouble codes. If they come up with a P-2716 code, you need a new Engine Control Unit (the computer). If your car has under 80,000 miles on it, Toyota will replace it for free.

Attach a diagnostic computer to the leads on your engine.
Check the codes to confirm that the onboard computer is choosing to shift under the correct conditions.

Or, get your local Dodge dealer (before they go bankrupt) to run the computer-diagnosis.

Sounds like you need the updated engine computer for harsh shifting. Look up under the glove box at the computer. Number should be 89661-02K21 if not, you need the update. It is an 8/80 warranty item.

I would definately take it back to the dealer and tell them they have not fixed the problem. The Dealer will hook the car up to the ODB II tester to get the codes from your cars computer as to what the computer thinks the problem is. Typically there is more than one oxygen sensor on the exahust system and the dealer ship may have replaced one and need to replace both - or they may have replaced one that was not faulty.

IF the check engine light went out when you left the dealer it is likely because they disconnected the battery when they worked on the car. The computer will then check a problem that shows up several times before lighting the check engine light (typically three cycles I believe - i.e. at least three consecutive starts and stops where the computer sees the same problem) so seeing the light out when it leaves the dealership does not mean they have fixed it, it merely means they have disconnected the battery. You should be well within your rights to go back and tell them they have not solved the problem and your not paying additional money for replacements of parts that didn't fix the problem.

As a check you should also take the car to a local Autozone (Car parts shop) and ask them to check the codes using the ODB II meter. At least then you can go to the dealer with the knowledge of what the computer code is and sound more knowledgable and less likely to be ripped off for poor workmanship.
