How to Fix P1375 Insufficient RPM Increase During Spark Test
If you’re experiencing the P1375 error code on your vehicle, it means that there is an insufficient RPM increase during the spark test. This can be a frustrating issue to deal with, but fortunately, there are some steps you can take to fix it. In this article, we’ll go over the causes of this error code and provide you with a step-by-step guide on how to fix it.
Causes of P1375 Error Code
There are several reasons why you might be experiencing the P1375 error code. Some of the most common causes include:
Faulty Ignition Coil
One of the most common causes of the P1375 error code is a faulty ignition coil. If the ignition coil is not functioning properly, it can cause a misfire in the engine, which can lead to the error code.
Bad Spark Plugs
Another common cause of the P1375 error code is bad spark plugs. If the spark plugs are worn out or damaged, they won’t be able to ignite the fuel in the engine properly, which can cause a misfire and trigger the error code.
Wiring issues can also cause the P1375 error code. If there is a problem with the wiring that connects the ignition coil to the engine control module (ECM), it can cause a misfire and trigger the error code.

Now that you know some of the common causes of the P1375 error code, let’s go over the steps you can take to fix it.
Step 1: Check the Ignition Coil
The first step in fixing the P1375 error code is to check the ignition coil. You can do this by using a multimeter to test the resistance of the coil. If the resistance is outside of the manufacturer’s specifications, you will need to replace the ignition coil.
Step 2: Inspect the Spark Plugs
Next, you should inspect the spark plugs to see if they are worn out or damaged. If they are, you will need to replace them. Make sure to use the correct type of spark plugs for your vehicle.
Step 3: Check the Wiring
If the ignition coil and spark plugs are both in good condition, the next step is to check the wiring. Make sure that the wiring is properly connected and that there are no breaks or damage to the wires. If there is a problem with the wiring, you will need to repair or replace it.
Step 4: Clear the Error Code
Once you have fixed the issue that was causing the P1375 error code, you will need to clear the code from the ECM. You can do this by using an OBD-II scanner or by disconnecting the battery for a few minutes.
