P0375 Timing Reference High Resolution Signal A No Pulses

P0375 Timing Reference High Resolution Signal A No Pulses: Causes, Symptoms, and Solutions

If you’re driving a modern car, chances are you’ve seen a “Check Engine” light on your dashboard at some point. This can be a frustrating experience, but with the right knowledge, you can diagnose and fix many of the common problems that trigger these lights.

One such problem is the P0375 code, which indicates that the Timing Reference High Resolution Signal A has no pulses. In this article, we’ll cover the causes, symptoms, and solutions for this code.

What is the P0375 code?

The P0375 code is a trouble code that is triggered when the PCM (Powertrain Control Module) detects that the Timing Reference High Resolution Signal A has no pulses.

This signal is responsible for providing the PCM with information about the position of the crankshaft and camshaft, which is essential for proper engine operation. When this signal is not detected, the engine may not start, or it may run poorly.

Causes of P0375 code

There are several potential causes of the P0375 code, including:

1. Failed crankshaft position sensor
2. Failed camshaft position sensor
3. Wiring issues
4. Failed PCM

Symptoms of P0375 code

If your car has triggered the P0375 code, you may experience one or more of the following symptoms:

1. Engine may not start
2. Engine may run poorly or stall
3. Poor fuel economy
4. Misfires
5. Illuminated Check Engine light

Solutions for P0375 code

Here are some of the potential solutions for the P0375 code:

1. Check the crankshaft position sensor – This sensor is located near the back of the engine and can be checked with a multimeter. If it’s faulty, it will need to be replaced.
2. Check the camshaft position sensor – This sensor is usually located on the front of the engine and can also be checked with a multimeter. If it’s faulty, it will need to be replaced.
3. Check the wiring – Make sure that all wiring is in good condition and properly connected. Look for any signs of damage or corrosion.
4. Check the PCM – This is the least likely cause of the problem, but it’s still worth checking. If the PCM is faulty, it will need to be replaced.

Conclusion

The P0375 code is a common problem that can be caused by a variety of issues. If you’re experiencing any of the symptoms listed above, it’s important to get your car checked out by a qualified mechanic. With the right diagnosis, you can get your car back on the road and running smoothly.
