What is P1607 Engine Code [Quick Guide]
DTC Dodge P1607 Short Explanation
What code is P1607 mean?
The P1607 code is a diagnostic trouble code (DTC) for “Internal Control Module Random Access Memory (RAM) Error”. This code indicates that there is an error in the internal RAM of the engine control module (ECM). The ECM uses RAM to store information about the engine and its performance. When the ECM detects an error in the RAM, it will set the P1607 code and turn on the Check Engine Light.
What does PCM internal shutdown timer rationality mean?

FAQ
What is code p1607?
The code P1607 is a diagnostic trouble code (DTC) for “Internal Control Module Memory Check Sum Error”. This code is stored when the powertrain control module (PCM) detects an error in the internal memory. This code can be caused by a corrupted or missing file in the PCM, or by an incorrect memory check sum.
How do I fix code p1607?
If your car is displaying code P1607, it means that there is a problem with the engine control module (ECM). The ECM is responsible for controlling the engine, and if it is not working properly, the engine will not run correctly. There are a few things that you can do to fix code P1607.
First, check the ECM fuse. If the fuse is blown, replace it with a new one. If the fuse is not blown, check the ECM for loose wires or bad connections. If you find any loose wires or bad connections, tighten or reconnect them as needed.
If the ECM seems to be working properly, the next thing to check is the engine itself. Make sure that all of the spark plugs are in good condition and that the spark plug wires are connected correctly. Also, check the engine oil level and make sure that the oil is clean and fresh.
If the engine still will not start, the last thing to check is the ECM itself. You may need to replace the ECM if it is not working properly.
What are the symptoms of code p1607?
The symptoms of code P1607 can vary depending on the vehicle, but typically includes the engine light being illuminated on the dash and the vehicle running rough. In some cases, the vehicle may not start at all. The code is most often caused by a problem with the vehicle’s computer, although it can also be caused by a faulty sensor or connection.
What causes code p1607?
There are a few things that can cause code P1607:
1. A problem with the battery or charging system
2. A problem with the PCM (powertrain control module)
3. A short circuit or open circuit in the wiring between the battery and the PCM
4. A failed PCM
How do I prevent code p1607?
There is no one definitive answer to this question as there are a number of potential causes for code p1607 to be displayed. However, some possible preventative measures that could be taken include ensuring that all electrical connections are secure and free of corrosion, regularly checking and replacing any worn or damaged parts, and following the manufacturer’s recommended maintenance schedule for the vehicle. Additionally, if the vehicle is equipped with an aftermarket alarm system, disabling it may also help to prevent code p1607 from being displayed.
