Diagnostic guide for P0017

Diagnostic Guide for P0017 - Crankshaft Position - Exhaust Camshaft Position Not Plausible

The P0017 code indicates a discrepancy between the crankshaft position and exhaust camshaft position signals. The goal of this diagnostic guide is to identify the root cause of the issue, which may involve checking oil levels, sensors, and timing components.

Safety Notes

Ensure the engine is cool before working. Use caution when working around moving parts and hot engine components. Disconnect the battery when inspecting electrical connections.

Step 1

Check Engine Oil Level and Condition

Instruction Inspect the engine oil level using the dipstick and check the oil condition for contamination or viscosity issues.

Expected result Oil level should be within the recommended range and oil should be clean.

If Pass If oil level and condition are acceptable, proceed to check the camshaft and crankshaft sensors.

If Fail If oil is low or contaminated, top off or change the oil and retest the system.

Step 2

Inspect the Camshaft and Crankshaft Position Sensors

Instruction Locate and visually inspect the exhaust camshaft position sensor and crankshaft position sensor for damage or disconnection.

Expected result Sensors should be securely connected and free from physical damage.

If Pass If sensors appear intact, proceed to test their electrical output.

If Fail If any damage or disconnection is found, repair or replace the affected sensor and retest.

Step 3

Test Sensor Output with a Multimeter

Instruction Using a multimeter, test the voltage output of the camshaft and crankshaft position sensors while the engine is running.

Expected result Both sensors should produce a consistent voltage signal within the manufacturer's specifications.

If Pass If both sensors are functioning correctly, check the timing chain or belt for wear or damage.

If Fail If either sensor output is out of specification, replace the faulty sensor and retest the system.

Step 4

Inspect Timing Chain or Belt

Instruction Remove any necessary covers to visually inspect the timing chain or belt for wear, stretching, or damage.

Expected result Timing components should be in good condition with no signs of wear or misalignment.

If Pass If the timing components are in good condition, check for blocked oil passages.

If Fail If any issues are found with the timing components, they may need to be replaced to resolve the P0017 code.

Step 5

Check for Blocked Oil Passages

Instruction Inspect the oil passages leading to the camshaft actuator for blockages or restrictions.

Expected result Oil passages should be clear and allow proper oil flow.

If Pass If oil passages are clear, consider checking for aftermarket oil additives that may affect performance.

If Fail If blockages are found, clean the passages and retest the system.
