SOURCE: I got the code 55 when I turned the key 3 times.

Code 55 indicates end of codes. If you are retrieving codes, code 55 will indicated that you have reached the end of the code list. Code 55 will always be reported regardless of if there is another code to report or not. If you don’t receive a code 55 when retrieving codes, the power limited light may be burned out (or you may not have done the code checking procedure correctly). Good work and keep me posted for any other questions you may have.

SOURCE: after turning the ignition key 3 times (without

Hi, these codes relate to your passenger side oxygen sensors. The first thing I would do is check the wiring on these sensors to make sure it hasn't come loose and melted its insulation on a hot pipe. I would also check the connections at the sensors to make sure the connectors are not loose. Repair any suspicious connectors or wires. While under the car, I would start it and check for an exhaust leak at the flage between the exhaust pipe and manifold. Repair any leaks. If all that was good, I would check the wires with an ohmmeter. To do this, disconnect the connectors and check the continuity of each wire from the connector at the sensor to the PCM. Disconnect the battery before taking the connector off the PCM. When testing the wires, there should be zero ohms from one end to the other, and each wire should have infinite ohms to chassis or engine ground. If the wires are all good, I would replace the sensors. Please let me know if you have questions and thanks for using FixYa.

I have a 2008 pt cruiser and I have 3 codes pop up they are. Sw ver 200. And cam over 431. Lin very. 429. What do they mean??

Those aren't error codes. To check error codes do this:
1. Place the key into the ignition.

2. Turn the key towards the windshield (without starting the engine) and back again.

3. Do the above 3 times and with the last turn the key left pointing forward (towards the windshield).

4. All three turns should be made within 5 seconds. (it's not hard).

If you did it right, in the middle dial where the odometer is, the fault codes stored in the computer will come up. Example: P0138

If there's no codes stored in the computer, it should read "done".

What is a red dot light in the center of the gauges and can it be reset

The red dot is a Security indicator and may mean Your
key fob lost a code. do the following
Turn the key ON-OFF-ON-OFF-ON within about 5 seconds. Your odometer will then display any codes one at a time. The displayed codes will start with a letter with three digit numbers. Something like P0123 or B1234 and you'll know it's done 'cause it will say "done".

Have a pen and pad readily and write the codes down. There's a DT Thread that has all of the Dodge codes and you can check it out for yourself

My dodge cummins has hard start problem and sometimes my dash display will say Done what does this mean it says it where the mileage readout is displayed

Not sure about your hard starting problem, but the Done in the odometer is the conclusion of the computer test. If you turned your key on and off 3 times, it activates the self-diagnosis and will show the codes of any problems you are having. If you are getting no codes, and just DONE, it's finding no problem.

Maybe a Dodge expert will pipe up and give you some ideas about the no-start. According to a quick google search, it seems your problem is relatively common.

"done" on the odometer?

If you turn the key on and off on a dodge 3 times in a row, they will give you trouble codes in the odometer area. After all the codes are displayed or if there are no codes it will say (done). There shouldn't be anything wrong with your car, it was just in diagnostic mode.

Check engine lights on

You don't have to get it scanned and pay...just put the key in the ignition and turn the car on-off-on-off-on (don't turn ignition on, just power), after 3 turns of the key if there are any trouble codes they should show up in your odometer. There will be "---" between code flashes and when it is done showing codes it will say "done". Google the specific codes it gives you and in a few places they have the full list of code meanings.
