O2 sensor (found just in front of the cat) or Power steering pressure sensor fault if it's a typo and should be P0551.
Ignore P1684 as it just means sometime in the last 50 starts the battery was disconnected

Car comes up with 91684 {car has been started 50 times battery disconnected} how do I reset?

Under Cruizin says: "apparently there are two different read-outs for the P1684 fault code and one is:

P1684 does not indicate a problem; it's only a status, which indicates that the PCM memory has been cleared within the last 50 ignition cycles. "Done" indicates that no DTC's are present and the procedure is complete.

We change the computer in our 2002 and there are 2 codes showing on the screen. P1684 & P1685

Code 1684 says the computer has lost battery voltage in the last 50 starts, and code 1685 means the security code in the key is not valid.
You may have to have the computer flashed by the dealer to match the original settings in the original computer.

Hello, i have a 2002 chrysler PT cruiser and it gives the error codes P1684 and P0700, the car is automatic and only goes on gears reverse and first. It does not shift up when driving. What can i do to fix...

It is very possible that the transmission is going out. Need a little more clarification on what the codes mean that are coming up.You can go to Autozone and they can bring up the codes, and then they will tell you what those codes mean. It doesnt cost anything and could possibly be a cheap, quick, and easy fix.

Errors P1684 given, how do I fix

The first code, p1684, just states the battery has been dis-connected in the last 50 start cycles.
Code p0401 is the EGR flow. You may need to replace the EGR valve.
Code p1193 is the intake air temperauture ( IAT) sensor. It may also need to be replaced.
Have your mechanic take a look at those, and please let me know how it goes.
