The hourly rate is the BLS Occupational Employment and Wage Statistics, May 2025 average pay for this trade in the US, $27.13 an hour, times 4 to 5.5 to cover what a shop bills (overhead, tools, insurance, profit). Parts are a band from budget aftermarket to the manufacturer part. Full method.

This is the range for the most common fix, timing chain replacement. Which repair your car needs depends on a proper diagnosis.
The computer compares signals from the crankshaft sensor and the camshaft sensor to confirm the engine's valves are opening in step with the pistons. On the bank with cylinder 1, those two signals do not line up. The timing may have shifted slightly, or one sensor is sending a bad signal.
- Safe to drive?
- Short trips only
- Most common cause
- Stretched timing chain or belt
Drive only if it runs smoothly; a stretched timing chain can skip a tooth, so stop if it runs rough or rattles.

What you may notice
- Hard starting
- Rough running
- Check-engine light on
- Rattle on startup
Common causes, most likely first
- Stretched timing chain or belt
- Worn tensioner or guide
- Failing crankshaft or camshaft sensor
- Timing marks off after past repair
- Dirty oil affecting the phaser
Check this first
Ask when the timing belt or chain was last serviced and whether the engine makes a rattle at cold start.

Before you pay
- Ask the shop what test showed this part is the cause, not just that the code appeared.
- Ask for parts and labor listed separately, and for the hours.
- Ask for a written OK before any extra work. Many states require written authorization before repairs.

P0016 questions
Is this serious?
It can be, because timing that is off can let valves hit pistons on some engines. If the car runs rough, rattles or has trouble starting, limit driving and get it checked soon.
How do I know chain or belt?
Your owner manual lists it. A belt sits behind a cover on the outside of the engine and needs replacement on a set schedule, while a chain lives inside the engine and often lasts much longer, but can stretch.
Could it just be a sensor?
Yes, and testing both sensors is a smart first step because it costs far less than opening the engine. A shop can compare the sensor signals on a scan tool to see whether the timing really moved.
