P0017 code – Camshaft Position

P0017 Code Causes Information & Fix

 The error code P0017 indicates a problem in the camshaft position correlation in bank sector I.

This article will look at what causes this problem and how to diagnose and fix the problem.

When you connect the OBD II scanner and read error code P0017, the engine camshaft and crankshaft are not properly aligned. These two important engine components work to control the timing of the engine.

They work with a reluctor ring that has a magnetic sensor. The ring generates a power current to show the position. The error code P0017 also indicates a problem associated with the camshaft sensor. The camshaft position sensor (CPS) is part of the huge fuel system in cars.

When the internal combustion engine is running, fuel and air have to mix for ignition, and this is where the camshaft sensors come in. The engine requires perfect timing of the fuel and air mixture during ignition; the camshaft sensors are responsible for this timing.

Wrong timing means the vehicle is going to experience misfires. For this correct timing to be achieved, the sensors work hand in hand with the onboard computer to determine the right timing.

If the sensor is faulty or missing, the onboard computer is useless since it receives the wrong signals. Wrong timing leads to problems such as losing vehicle power and difficulty starting the car. These cause the engine light on the dash to come on.

The camshaft position sensor also records the rotation rate of the camshaft and sends this information to the onboard computer.

Symptoms of error code P0017

The signs and symptoms of the P0017 error code vary depending on the extent of damage and the cause of the problem. The following are the most common symptoms of the P0017 error code.

• The engine warning light comes on
• Difficulty in starting the car
• Rough vibrations and car movements when accelerating
• Reduced fuel efficiency due to the camshafts being in the wrong positions
• Poor engine performance that causes poor acceleration
• The engine rattles noisily

Causes of error code P0017

The crankshaft and camshaft work to control the timing of the engine. When they are out of position for any reason, the vehicle’s performance is heavily affected. It is a serious issue and should be fixed immediately for a better ride and to prevent further engine damage that may be very expensive.

Worn-out distribution chain

The timing chain or distribution chain is a series of links in the chain. The chain is located just in front of the motor. It is connected to pulleys and gears that control the movement of the system’s mechanical components, such as the crankshaft and camshaft.

The distribution chain must move smoothly around the gears for the engine to fire properly. Since the chain is susceptible to wear and tear, it may break occasionally.

Damaged crankshaft sensor

It is a problem associated with the camshaft sensor. The camshaft position sensor (CPS) is part of the huge fuel system in cars. When the internal combustion engine is running, fuel and air have to mix for ignition, and this is where the camshaft sensors come in.

The engine requires perfect fuel and air mixture timing during ignition; the camshaft sensors are responsible for this timing. Wrong timing means the vehicle is going to experience misfires.

For this correct timing to be achieved, the sensors work hand in hand with the onboard computer to determine the right timing. If the sensor is faulty or missing, the onboard computer is useless since it receives the wrong signals.

Misaligned timing chain

If the distribution chain is out of its line due to impact when driving, you might get a P0017 error code. This is because the timing in the engine is affected, which in turn affects the camshaft and crankshaft.

Engine timing problems

Camshaft timing regulates the pistons and valves with the help of a timing or distribution belt. The engine can suffer damage if the timing is off for any reason. In some vehicle designs, this problem is worse as the engine valves and pistons are located in the same area.

If you have a timing issue, you could have to rebuild and replace the engine. This will cause the camshaft and crankshaft to fall out of position leading to a P0017 error code.

Blocked oil pathways

Engine oil is required for many functions in the engine, including lubrication and heat regulation. When oil is not flowing as it should, the camshaft and crankshaft can easily overheat and fall out of their lines. This will cause a P0017 error code on the OBD II scanner.

How to fix error code P0017

To diagnose and fix your car, you will need the following tools: an OBD II scanner, a digital multimeter, and an oscilloscope. You can diagnose and fix your car in your home garage using the following steps.

1. Use the OBD II scanner to scan the vehicle for other error codes. For some vehicle makes, the P0017 error code may appear together with P0009, P0016, P0019, and P0008.
2. This is because these error codes represent almost similar malfunctions around the camshaft and crankshaft. If the P0017 error code is present, it helps you identify the problem: in the camshaft and crankshaft.
3. After knowing where the problem lies, visually inspect the camshaft and crankshaft and all their components, especially the wires. If you find any loose, damaged, or eroded wires, replace them immediately, as they might be the cause of the problem. Tighten all connections before moving to the next step.
4. Use the OBD II scanner to read the freeze frame data. This will reveal the conditions that caused the code. Clear the code, then do a test drive.
5. Use the oscilloscope to read and observe the crankshaft and camshaft patterns. There should be a regular pattern. However, the problem will likely be in the tone ring if there isn't one.
6. Check the tone rings and inspect their alignment. Also, visually inspect and look at their condition. For this step, you will need extra equipment, which is: cam gear and a harmonic balancer. If they are broken or damaged, replace them immediately.
7. Check the timing/distribution chain; if it is out of alignment, check the tensioners that hold it together. If the tensioner is damaged, it means the distribution chain is misaligned. Replace it if it is damaged and reposition it.
8. Check the oil for its viscosity, ensuring it is correct for your engine. If the oil is bad, drain it and replace it with fresh oil.
9. Test the crankshaft and camshaft using the digital multimeter. Compare the readings to the correct readings in the car manual. The readings should be similar to ensure the error code is gone.

Conclusion

The camshaft and crankshaft are important components of the engine. When they are misaligned, it could cause serious engine damage. This is why it is important to get it fixed once you have identified a symptom.
