How to Fix Code P1345 Chevy

By

If you have a Chevy and it’s giving you the P1345 code, don’t worry. This is a common issue and there are a few things you can do to fix it. First, check all of your spark plugs and wires.

If they are old or worn out, replace them. Next, clean the Mass Air Flow sensor. This is usually the cause of the P1345 code.

Finally, check your fuel pressure. If it’s low, that could be causing the code as well.

P1345 code fix! Chevy, GMC, Silverado, suburban etc

  • Check for loose, damaged, or corroded wiring and connectors
  • Clean all the grounds (battery, engine, chassis)
  • Test the crankshaft position sensor and replace if necessary
  • Inspect the camshaft position sensor and replace if necessary
  • Check for proper engine timing
  • Replace the ignition control module if necessary

What is Code P1345 Chevy

If your Chevy is displaying code P1345, it means that the powertrain control module (PCM) has detected a problem with the camshaft position sensor signal circuit for cylinder number 8. The PCM uses this signal to determine when the pistons are at top dead center so that it can properly time the ignition and injector pulses. If there is an issue with this signal, it can cause all sorts of problems including engine misfires, poor fuel economy, and stalling.

To diagnose code P1345 on your Chevy, you’ll need a OBD-II scanner and a multimeter. First, clear the codes and take your vehicle for a test drive to see if the code comes back. If it does, then you’ll need to check the voltage of the camshaft position sensor signal wire at cylinder 8.

It should be between 0.5-0.7 volts AC. If it’s not within that range, then there is likely an issue with the sensor itself or its wiring harness. Once you’ve ruled out those possibilities, then you’ll need to check for proper ground connections at both ends of the circuit (the sensor and PCM).

A loose or corroded ground connection can often times be the root cause of these types of issues. If everything looks good there, then you may have a faulty PCM which will need to be replaced by a professional mechanic or dealership service department.

How Do I Fix Code P1345 Chevy

If your Chevy is displaying code P1345, it means that the powertrain control module (PCM) has detected a problem with the camshaft position sensor signal. This code can be caused by a number of different issues, so it’s important to diagnose the problem properly in order to get it fixed. One common cause of code P1345 is a failing camshaft position sensor.

The sensor itself may be faulty, or there could be an issue with the wiring or connector. If the sensor is not working correctly, it will send incorrect information to the PCM which can lead to engine performance problems. Another possibility is that there is something blocking the sensor, such as debris build-up on the lens.

Another potential cause of code P1345 is an issue with the timing chain or belt. If these components are stretched or damaged, they can cause misalignment between the crankshaft and camshaft resulting in incorrect signal from the camshaft position sensor. In some cases, code P1345 may be caused by a software issue within the PCM itself.

In this case, a simple reset of the PCM may fix the problem.

What are the Symptoms of Code P1345 Chevy

If your Chevy is experiencing any of the following symptoms, it may have a P1345 code: -Rough idle -Engine misfire

-Decreased fuel economy -Check Engine Light is on One of the most common symptoms of code P1345 Chevy is a rough idle.

If your engine is idling roughly, it may be an indication that there is an issue with the timing chain or belt. Another symptom you may notice is an engine misfire. If your engine is misfiring, it means that one or more cylinders are not firing correctly.

This can lead to decreased fuel economy and performance. Finally, if you see the Check Engine Light come on, this could be an indication of code P1345.

What Would Cause This Code to Be Triggered

Assuming you are referring to the code snippet: if (expression) { // Statements executed when the condition is true

} There are a few different things that could cause this code to be triggered. First, the expression being evaluated could return a value of true.

Second, the expression could be a comparison operator that returns true based on the values being compared. Lastly, the expression could be a boolean variable that has been set to true.

Conclusion

If you have a Chevy and it’s giving you the code P1345, don’t worry. This is a common problem that can be fixed fairly easily. The first thing you need to do is check all of your spark plugs and wires.

If they are old or worn, replace them. Next, check your camshaft sensor. This is located on the front of the engine, near the timing belt.

If it’s damaged or dirty, replace it. Finally, make sure your crankshaft sensor is working properly. This is located at the back of the engine, near the oil filter housing.

If it’s not working properly, replace it.
