What is Code P1633?

Code P1633 is a diagnostic trouble code (DTC) that is associated with the OBD-II system. It is commonly referred to as the “Camshaft Position Sensor A Circuit Range/Performance” code. This code is set when the PCM (Powertrain Control Module) detects a problem with the camshaft position sensor (CMPS) A circuit.

The CMPS A circuit is responsible for sending a signal to the PCM that indicates the position of the camshaft. This signal is used by the PCM to synchronize the ignition timing and fuel injection. If the PCM detects a problem with the CMPS A circuit, it will set Code P1633.

What causes Code P1633?

There are a number of different things that can cause Code P1633. Some of the most common causes include:

  • A faulty camshaft position sensor (CMPS)
  • A damaged or corroded CMPS wiring harness
  • A problem with the PCM

In some cases, Code P1633 can also be caused by a problem with the crankshaft position sensor (CKPS). However, this is less common than a problem with the CMPS.

How to fix Code P1633?

The first step in fixing Code P1633 is to diagnose the problem. This can be done by using a scan tool to read the codes and check the live data. Once the problem has been diagnosed, the next step is to fix it.

If the CMPS is faulty, it will need to be replaced. If the wiring harness is damaged or corroded, it will need to be repaired or replaced. If the PCM is the problem, it will need to be repaired or replaced.

In some cases, Code P1633 can be fixed by simply clearing the code and resetting the PCM. However, this is not always a permanent fix. If the code comes back after the PCM has been reset, it is likely that there is a problem with the CMPS, wiring harness, or PCM.

Code P1633 can be a frustrating problem to deal with. However, it is usually a relatively easy problem to fix. By following the steps in this guide, you can diagnose and fix Code P1633 in no time.

How to diagnose Code P1633?

Code P1633 is a generic OBD-II trouble code that indicates that there is a problem with the camshaft position sensor (CMPS) circuit. The CMPS is a sensor that tells the engine control module (ECM) the position of the camshafts. This information is used to synchronize the fuel injection and ignition timing.

When the ECM detects a problem with the CMPS circuit, it will set Code P1633. This code can be caused by a number of problems, including:

  • A faulty CMPS
  • A damaged wiring harness
  • A problem with the ECM

To diagnose Code P1633, you will need to:

1. Check the wiring harness. Inspect the wiring harness for damage, corrosion, or loose connections. If you find any damage, repair it or replace the harness.
2. Test the CMPS. Use a multimeter to test the CMPS for resistance. The resistance should be within the specifications listed in your vehicle’s service manual. If the resistance is not within specifications, replace the CMPS.
3. Test the ECM. Use a scan tool to test the ECM for codes. If the ECM has any other codes, they may be related to Code P1633. If the ECM has no other codes, it is likely that the problem is with the CMPS or the wiring harness.

Once you have diagnosed the problem, you can fix it by repairing or replacing the faulty component.

How to fix Code P1633?

To fix Code P1633, you will need to:

1. Repair or replace the faulty CMPS. If the CMPS is faulty, it will need to be repaired or replaced.
2. Repair or replace the damaged wiring harness. If the wiring harness is damaged, it will need to be repaired or replaced.
3. Reprogram the ECM. If the ECM has been damaged, it may need to be reprogrammed.

Once you have repaired or replaced the faulty component, you will need to clear the code from the ECM. You can do this by disconnecting the battery for a few minutes, or by using a scan tool.

If the code returns after you have repaired or replaced the faulty component, you may need to take your vehicle to a qualified mechanic for further diagnosis.

Code P1633 can be a frustrating problem, but it is usually easy to diagnose and fix. By following the steps in this guide, you can get your vehicle back on the road in no time.

Here are some additional tips for diagnosing and fixing Code P1633:

  • If you are not comfortable working on your vehicle, take it to a qualified mechanic.
  • Make sure to use the correct tools and procedures when working on your vehicle.
  • Be careful not to damage any components when working on your vehicle.
  • If you are unsure of what you are doing, do not attempt to fix the problem yourself.

By following these tips, you can safely and effectively diagnose and fix Code P1633.
