P1684, P0622, P0403, P0134. These are the codes that I got from my scanner, what do they mean? Thank you

These codes showed up after, I replaced the battery and alternator with news ones. The battery light will not turn off. Can someone assist with these codes P1684= manufacturer control auxiliary inputs auxiliary outputs, P0622= generator F-term. field control , P0403= EGR flow circuit malfunction, P0134= 02 sensor CKT activity (bank 1 sensor 1).

My guess is you may have wired something up wrong, or installed a faulty part. Either that or forgot to plug something back in while you were putting it back together. In other words replacing a battery and alternator shouldn't cause the oxygen sensor to go bad. So my suggestion is to check all plugs and wires to make absolutely certain everything is put back together correctly before you sink more money into fixing what's not broken. Haynes repair manuals list all the engine fault codes so for everyone else reading this, if you get codes check your manual or head to the library to look it up in theirs.

SOURCE: P0134 Error Code

The code refers to an oxygen sensor that is no longer detecting changes in fuel delivery by way of sensing exhaust oxygen content. Bank 1, sensor 1, tells you which sensor is bad, in this case, it's the sensor that is mounted before the catalytic converter, on the rear bank of cylinders as you look into the engine compartment. It would really be a good idea to change both pre-cat O2 sensors at this point as they are both twelve years old.

I have a 2000 dodge intrepid 2.7 with trouble codes p1684 and 0622 but already replaced battery and alternator still won't stay charged???

Dodge codes p1684
For Chrysler vehicles, a code P1684 represents a battery disconnected within last 50 starts. Although the code signifies a battery-related issue, diagnostic codes do not tell you how to proceed with repairs. It is the job of a trained professional to further diagnose and repair the problem.

What does a confirmed code mean.states p0403 confirmed cel light stays on after replacing part

Did you reset the light after the part replacement? If you reset the light, the should read that the light is off (or show 'no codes') before the engine is started. If the light comes back on right away, with the same code, then replacing the part did not correct the problem.
A confirmed code simply means that the problem actually exists. For many codes, the first occurrence will not turn on the light. But if the situation happens again within a specific interval, it confirms the code and lights the light. Many scanners can also see the 'pending' codes (the first occurrence).

2002 Chrysler PT cruiser has only 28,000 miles the engine light came on. I retrieved error codes p0134, p1684 and P1685. I found a list of the codes but no description. Can you tell me what these mean

I found the codes & basic (VERY basic) descriptions from these sources:

Code P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1) - something to do with the O2 sensor circuit, but beyond that I'm not sure.

Code P1685 Skim Invalid Key - Security system issue. I got this answer from the Dodge Forum:

"The Sentry Key Immobilizer Module (SKIM) is part of the security system and kills the vehicle when a wrong key is used. There may be a problem with your key or the chip reader in the ignition switch. This is something the dealer will need to determine for sure. This code will also be set if someone actually tried to steal the vehicle."

Hope this helps.

2001 Dodge Intrepid- What does P0622= Generator F-term. Field F control, and P0403= EGR flow circuit malfuntion mean? Thank you

If you've replaced those parts according to the codes, you need to have the codes cleared from the computer, otherwise the car will think you still have the bad parts on, and stay in what they call Limp Mode! Sometimes you can take it to an Autozone, and they can clear it for you! Otherwise you need to have a shop clear those computer codes for you!

P0134 code

Since you are asking where the O2 sensors are, you may already have the answer to this question.
Code 134 is for no activity from bank one sensor one, which is in front of the catalytic converter. The sensor would need to be tested with a scanner.

Get code P0403 on 2001 Dodge Caravan...even after I just replaced the EGR valve twice (first replaced as thought might be faulty) cleared a few other codes related to EGR flow, but the P0403 ke

if you have a obd11 scanner, clear the codes and drive the vehicule for a while ,a good half an hour or so above 30 mph. this will give your onboard computer a chance to relearn system settings.if the code comes back there could be some other sensor malfunctioning or a problem with the onboard computer.ex corroded connections or broken pins.

Car won't start there is power to the starter. Starter is new. p1684 code the dash lights reset and says done and the the code p1684 comes on. Also you can not tell what gear the car is in there...

I just wanted to show you what I found on the internet regarding p1684:
"P1684 engine code

The P1684 code simply means that the battery has been disconneted within the last 50 starts."
