If your Mazda is experiencing a P0725 code, it will likely result from an engine speed signal circuit malfunction. During the CCM rationality test, this code is triggered when the PCM detects the engine speed signal indicating less than 300 rpm for more than 10 seconds. This code can have several causes, ranging from an intermittent fault with the CMP sensor signal to an open or shorted PCM to a TCM circuit or even a failed TCM or PCM. To help you understand these causes and their solutions, we have created a table of causes and solutions below.

Table of Causes and Solutions for Mazda P0725 Code
| Cause | Solution |
|---|---|
| CMP sensor signal erratic or missing (an intermittent fault) | Check the CMP sensor and replace it with a new one if needed |
| PCM to TCM circuit open or shorted to ground | Check the PCM to TCM circuit and repair any open or short circuits |
| TCM has failed | Replace the TCM with a new one |
| PCM has failed | Replace the PCM with a new one |
If you are experiencing a Mazda P0725 code, it could result from an engine speed signal circuit malfunction. During the CCM rationality test, this code is triggered when the PCM detects the engine speed signal indicating less than 300 rpm for more than 10 seconds. There are a variety of causes for this code, from an intermittent fault with the CMP sensor signal to an open or shorted PCM to a TCM circuit or even a failed TCM or PCM. To help you diagnose and repair this issue, we have compiled a table of causes and solutions below.
CMP Sensor Signal Erratic or Missing
If the CMP sensor signal is erratic or missing, it is likely an intermittent fault that needs to be addressed. The first step is to check the CMP sensor and replace with a new one if required. This should solve the problem.

PCM to TCM Circuit Open or Shorted to Ground
If the PCM to TCM circuit is open or shorted to ground, the Mazda P0725 code can be triggered. To solve this issue, check and repair any open or short circuits in the circuit, if necessary. This should fix the problem.
Failed TCM or PCM
A failed TCM or PCM can cause the Mazda P0725 code. In this case, you must replace the TCM or PCM with a new one, which should solve the issue.
Conclusion: Diagnosing and Solving Mazda P0725 Code
If your Mazda is experiencing a P0725 code, diagnosing and solving the issue correctly is important. The causes for the code can range from an intermittent fault with the CMP sensor signal to an open or shorted PCM to TCM circuit or even a failed TCM or PCM. To help you diagnose and repair this issue, we have compiled a table of causes and solutions for the Mazda P0725 Code above. With this information, you should be able to diagnose and repair the issue with your Mazda correctly.
