What Does Toyota Prius Code P0016 Mean?

  • Toyota Prius P0016 definition: The correlation of the camshaft and crankshaft positions on bank 1 is incorrect based on the intake camshaft position sensor.
  • Issue Severity: SEVERE – Stop driving immediately
  • Repair Urgency: Fix this code immediately (same day if possible) to avoid internal engine damage.
  • Diagnosis: This trouble code can cause the vehicle to be hard to start and run rough. In some cases, the vehicle may not be driveable. It should be addressed as soon as possible.

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 does this by monitoring them using the Camshaft Position Sensor(s) and Crankshaft Position Sensor. 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.

How Much Does It Cost to Fix Toyota Prius Code P0016?

P0016 can be caused by anything from a stretched timing belt or chain to a bad sensor to dirty oil. It’s impossible to give an accurate estimate without properly diagnosing the issue first.

If you take your car to a shop for diagnosis, most shops will start with an hour of “diag time” (the time spent in labor diagnosing your specific issue). Depending on the shop’s labor rate, this typically costs somewhere between $75-$150. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P0016 code.

For error code P0016, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.

  • Engine oil and filter change $20-$60

DIY Steps to Diagnose Toyota Prius Code P0016

Engine code P0016 could be caused by a number of things, including a stretched timing belt or chain, a bad sensor, or even dirty oil. If you’d like to try to fix code P0016 at home without throwing money at parts, you’ll want to follow the steps below for proper diagnosis. Keep in mind this is an advanced-level diagnosis and repair and not recommended for beginners. Diagnosis requires more specialized equipment beyond what the FIXD Sensor can provide and it can be a time and labor-intensive process for inexperienced DIYers.

DIY difficulty level: Advanced

This repair requires mechanical knowledge and is not recommended for beginners.

Tools/parts needed:

  • FIXD
  • Basic Hand Tools
  • Vehicle-Specific Service Manual
  • Oscilloscope


Use FIXD to scan your vehicle to verify P0016 is the only code present.


Check the oil level and if incorrect, correct to the proper level. If it’s dirty, replace the engine oil and filter. Clear the code, and see if it comes back.


Check for any Technical Service Bulletins (TSB) for your make and model vehicle. For example, certain General Motors vehicles (GMC, Chevrolet, Buick, Cadillac) have a known issue with stretched timing chains, which can cause this fault. If a TSB applies to your vehicle, perform this service first.


This code requires an oscilloscope for proper diagnosis. Not all shops are equipped with this but many are. Using the O-scope (oscilloscope), connect to the signal wire for the crankshaft position sensor and bank 1 and bank 2 (if equipped) camshaft position sensors and compare the three (or two) to each other. If they are offset from their proper locations, a stretched timing chain, jumped timing, or a slipped reluctor ring is the issue. Replace the necessary parts to resolve the concern.

Common Toyota Prius P0016 Diagnosis Mistakes

Not checking for TSBs before starting diagnosis.
