If your vehicle has this fault and you’re not comfortable diagnosing this issue at home, we recommend finding a RepairPal certified shop nearby to pinpoint the problem and give an accurate estimate for repairs. With a cam or crank position sensor fault, the first step is to get it diagnosed to figure out what is causing the problem. No noticeable adverse conditions in some cases.P0016 is not one of the top 5 trouble codes for the Ford Expedition but, it is still a common one.Slipped reluctor ring on bank 1 exhaust camshaft.Slipped reluctor ring on the crankshaft.There are many potential causes of code P0016. The chart below shows the most likely repair and cost range for Expeditions for all of the years that FIXD has data on. Most Likely Repair And Cost For Ford Expedition P0016 By Year If the Engine Control Module (ECM) detects that the bank 1 intake camshaft and crankshaft are not in the correct position, it will trigger code P0016. It does this by monitoring them using the Camshaft Position Sensor(s) and Crankshaft Position Sensor. In order for the engine to run smoothly and efficiently, it has to know exactly what positions the camshaft and crankshaft are in their rotation. It should be addressed as soon as possible. In some cases, the vehicle may not be driveable. Diagnosis: This trouble code can cause the vehicle to be hard to start and run rough.Repair Urgency: Fix this code immediately (same day if possible) to avoid internal engine damage.Issue Severity: SEVERE – Stop driving immediately.Ford Expedition P0016 definition: The correlation of the camshaft and crankshaft positions on bank 1 is incorrect based on the intake camshaft position sensor.If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.What Does Ford Expedition Code P0016 Mean? The cam and crank should be precisely timed together.
What ties these two shafts and their sensors together is the timing belt or chain. The PCM uses the CMP signal to identify the beginning of the injector sequence. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM.
It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The crankshaft sensor is part of the primary ignition system and functions as the “trigger”. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position. The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. What does the code mean? OBD-ii Code P0016 definition:
