Well, the code 12 is telling you the battery or the computer has been disconnected in the last 50 starts, code 21 is a problem with the O2 sensor, and code 55 is telling you there are no more trouble codes stored in memory.
Code 21 means the O2 sensor is not switching from rich to lean, which can be a faulty sensor or a fuel problem.

Code 12 is: Direct battery input to PCM was disconnected within the last 50 key-on cycles.

Code 21 is: Neither rich nor lean condition detected from the oxygen sensor input or oxygen sensor input voltage maintained above the normal operating range.

A P1698 code is described as PCM Fault, No CCD Messages from TCM Conditions. It's triggered when the key is on, and the PCM did not detect any CCD messages from the Transaxle Control Module (TCM) for 10 seconds. Time for a trip to the dealer unless you feel like inspecting the wires & connectors leading to/from the TCM. Usually I tell people to go to the dealer when there are TCM problems! They can read any codes stored in the TCM that a regular code reader can't get. Good luck.

Since yours is a forward engine car. The transaxle must be located in the front.

That is a code for the secondary (spark) circuit on cylinder number 3. It is usually caused by a bad connection between the coil and the plug (take the coil off the plug and check for moisture in the boot). If not, it might be a bad coil...

SOURCE: Dodge Gr Caravan error codes U0155, U110C, U0140

you are incorrect on your code read. u0155 is lost comm with IPC, u110c is no fuel read, u0140 lost comm with BCM and can all be fixed with a new BCM.

Automatic transmission locked up in 1999 dodge grand caravan


You can try having the computer checked for trouble codes, but chances are the problem will be inside the transaxle.

I have a 2011 dodge caliber and it isz throw a c0700 code could u tell me what this is


P0700 DODGE - Transaxle Control System Malfunction

Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Driveability problems
- Transaxle shifting problems

Possible causes - Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module

Tech notes Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem.

P0700 DODGE Description The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.
CLEAR THE CODES AND SEE IF IT RESETS. MOST LIKELY NOT A PROBLEM

My speedometer doesn't work, where is the wire located? it's a 2003 grand caravan se.


Your speedometer is controlled from your transaxle which is controlled by the computer. Usually a bad VSS sensor causes the speedometer malfunction. Are you getting any codes?

Check engine code 55 for 89 dodge caravan, obd11 code 55 for 89dodge caravan


55 is the "end of codes" code. If you only get this, then your vehicle has no stored codes.

Van shakes while driving


I've had several of these vans with this problem, check the transaxle for low fluid. Each of mine would start shaking when the fluid was low.

Transaxle control module


I have a 1993 Caravan with a 4speed trans.. I had to replace the transaxle control module. I paid $50.00 for it at a auto salvage yard and It corrected the problem. My trans would either go into limp mode or act like it was in Neutral.
