What is the problem on 2001 dodge caravan p1601


Hi Marvin, I'm glad to help! The 2001 Dodge Caravan does not have a code P1601. There's a code P1602 for PCM Not Programmed, but if that were the case the engine would not start and run. I suggest clearing the code and see if it comes back, if it does, then have the PCM Re-Programmed and see what happens. Hope this helps and have an awesome day Marvin.

Low oil pressure, trucks runs rough after it warms up, can not drive highway speeds it jumps and spits


Have you tried to replace the oil pressure sensor - it helps regulate your oil pressure in your vehicle. Not an expensive part but they do go out from time to time.

What is code p 1601


CHEVROLET DTC P1601 - Serial Comm. Problem With Device 1

The Powertrain OBD System Check prompts the technician to complete some basic checks and store the freeze frame and failure records data on the scan tool if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored on the scan tool for later reference.

The UART serial data circuit must be OK so the IPC can send the password XXXXX to the PCM. A DTC P1601 being set would indicate that the UART serial data circuit cannot be used to send information and causing the P1629 also.

An IPC theft deterrent DTC being set would indicate that the Passlock System is faulty and not sending a password XXXXX the PCM. Additional information can be found in Accessories and Optional Equipment / Antitheft and Alarm Systems. See Accessories and Optional Equipment\Antitheft and Alarm Systems

After any Passlock System parts have been replaced, the PCM must relearn the password XXXXX these components.

Replacement PCM's must be reprogrammed. Refer to the latest Techline information for programming procedures.

If no faults have been found at this point and no additional DTC's were set, refer to Diagnostic Aids for additional checks and information.

Hope helps (remember to rate this answer).

Truck turns over wont crank p1601 , u1255


These two error codes may be related. The p1601 is saying that the internal temperature of the power control module PCM is too high or that the outside temperature is out side of normal range. The second code u1255 is set when control modules fail to send the right signals to one another. If the PCM is malfunctioning due to high temperature or error then this may cause the lack of data transfer and hence the u1255 signal. Disconnect the negative terminal to the battery. Check out the PCM, ensure that all electrical connections to it are clean and secure; a poor connection can generate quite a lot of heat hence the p1601. Ensure that there is no sign of wires shorting underneath the PCM. If all connections look clean and free of corrosion open up the PCM and look for obvious hot spots on the main board. A dry joint or annular crack in the solder around a power pin on the board can create heat. If you see this just re-solder. If the board is cooked beyond repair then a new PCM is needed. Ensure that the PCM is shielded from direct sources of heat such as the exhaust manifold etc. When the battery is reconnected the error codes most likely will have been cleared but if the problem persists the error codes will be logged again.
