Can dirty oil cause P0017?

Yes, dirty oil can potentially cause the P0017 diagnostic trouble code to be set in a vehicle's engine control system. The P0017 code indicates a problem with the camshaft position sensor or its circuit, which can be influenced by the condition of the engine oil.


What is the P0017 Code?


The P0017 diagnostic trouble code is related to the camshaft position sensor circuit. It indicates that the engine control module has detected a problem with the correlation between the crankshaft position sensor and the camshaft position sensor. This can lead to issues with the engine's timing and performance.


How Can Dirty Oil Cause P0017?


Dirty or contaminated engine oil can contribute to the P0017 code in a few key ways:



  • Increased Wear on Sensors: Over time, dirty oil can cause increased wear and tear on the camshaft position sensor, leading to sensor failure or inaccurate readings.

  • Oil Sludge Buildup: Excessive oil sludge and deposits can interfere with the proper functioning of the camshaft position sensor, causing it to provide inaccurate signals to the engine control module.

  • Oil Starvation: Dirty oil that is not effectively lubricating engine components can lead to increased friction and wear, potentially causing the camshaft to fall out of sync with the crankshaft, triggering the P0017 code.


It's important to note that while dirty oil can contribute to the P0017 code, it is not the only possible cause. Other factors, such as a faulty camshaft position sensor, wiring issues, or timing chain problems, can also trigger this diagnostic trouble code.


Preventing and Resolving P0017 Issues


To prevent and resolve P0017 issues related to dirty oil, it is recommended to:



  • Maintain a Regular Oil Change Schedule: Follow the manufacturer's recommended oil change interval to ensure the engine is running with clean, fresh oil.

  • Use High-Quality Engine Oil: Choose an oil that meets or exceeds the vehicle manufacturer's specifications to provide optimal lubrication and protection.

  • Address Any Underlying Issues: If the P0017 code persists even after an oil change, it may be necessary to have the vehicle inspected by a qualified mechanic to identify and address any other underlying issues, such as sensor or timing chain problems.


By maintaining a clean, well-lubricated engine, you can help prevent the P0017 diagnostic trouble code and ensure your vehicle's engine is operating at its best.

What can throw a camshaft position sensor code?


The most common cause is a failing or a defective camshaft position sensor. Other problems can include circuit issues, like loose connections or damaged wiring, errors with the PCM, or a damaged reluctor wheel for the camshaft position sensor.



Can low oil damage a camshaft?


Damaged Camshaft: Low oil levels or pressure can cause a camshaft to wear prematurely due to insufficient lubrication. The camshaft controls the timing of the engine's valves, and when it wears out, it can produce misfires, rough idling, added fuel consumption, and reduced engine power, among other issues.



Can low oil cause camshaft position sensor code?


Camshaft sensor issues are caused by low engine oil or oil contamination, affecting valve timing. Alternatively, an issue with the wiring or timing chain might also be the culprit.



Can too much oil damage crankshaft?


Yes, excessive oil can cause aeration, overheating, and issues with the crankshaft, which can result in costly repairs.



Can oil affect the crankshaft sensor?


Oil should not be getting onto the crankshaft sensor unless there is a leak somewhere. You could have a rear main oil seal on the crankshaft seeping out oil. Or the valve cover gasket could be leaking and oil is running down behind the engine.



What is the most common cause of P0017?


This code indicates that your car's powertrain control module (PCM) detects a misalignment between the crankshaft and camshaft positions. A damaged or stretched timing belt, a bad crankshaft/camshaft sensor, a defective VVT actuator, and low oil levels are some of the issues that can trigger the code.



What kills crankshaft sensor?


Electrical Problems
Loose, worn-out, or damaged wiring can disrupt signals sent to and from the crankshaft sensor, causing it to malfunction.



Can old oil cause engine knock?


If your oil hasn't been changed in a while, dirt can accumulate in the lifters, leading to a persistent knocking noise every time you start the engine. Lifters can also become clogged when you use the incorrect grade of oil for your engine.



What are the symptoms of dirty engine oil?


Engine Knocking Noises

  • Increased Engine Heat. Dirty or old oil can't dissipate heat efficiently, and as a result, your engine might start running hotter than usual.
  • Reduced Fuel Efficiency.
  • Dark, Dirty Oil.
  • Check Engine Light.
  • Decreased Performance.
  • Smoke from the Exhaust.
  • Unusual Smells.



What happens to an engine with dirty oil?


Without proper cooling, the engine can overheat and can cause issues like a blown head gasket. If not replaced, dirty oil eventually turns into a thick dark sludge. Sludge can gum up your engine to the point where parts may struggle to move freely.
