Two is typical: most modern V6 engines with dual overhead cams have two camshaft position sensors—one on each cylinder bank.
What is a camshaft position sensor?
A camshaft position sensor (CMP) tells the engine control unit where the camshaft is in its rotation. This information helps manage fuel injection and ignition timing, and it is especially important for engines with variable valve timing. In a V6 with two cylinder banks, CMP sensors are usually positioned to monitor cam timing on each bank, ensuring coordinated operation of the intake and exhaust cams.
Typical count on V6 engines
In the majority of modern V6 engines with dual overhead cams, there are two camshaft position sensors—one sensor on each cylinder bank. This setup provides reliable timing signals for both banks and supports advanced timing strategies. The crankshaft position sensor remains a separate reference used by the engine management system.
Exceptions and variations
Some engines employ different layouts. A few older or specialized V6 designs may use a single CMP sensor that serves multiple cams, or additional sensors for redundancy or more complex timing schemes. The exact sensor count depends on the engine family and generation. Always confirm with the specific vehicle’s service manual or parts diagram.
Where to find the sensors
On most DOHC V6 engines, CMP sensors are mounted near the cylinder heads or timing covers on each bank. They read a reluctor ring or gear on a camshaft to generate timing signals for the ECU. Exact locations vary by make and model, so consult the repair guide for your vehicle.
Summary
For a typical modern V6, you can expect two camshaft position sensors—one for each bank. Some designs may differ, so when diagnosing timing issues, verify the exact configuration for your specific engine in the official manual or parts catalog.
How much does it cost to replace two camshaft sensors?
The average cost for a Camshaft Position Sensor Replacement is between $214 and $321. Labor costs are estimated between $105 and $154 while parts are priced between $108 and $167. This range does not include taxes and fees, and does not factor in your unique location.
How can I tell which camshaft sensor is bad?
How To Check if a Camshaft Position Sensor is Bad?
- Step 1: Check for Diagnostic Trouble Codes. A faulty CMP sensor will typically set one or more DTCs on vehicles model year 1996 or newer.
- Step 2: Perform a Visual Inspection. Next, you can move on to performing a visual inspection.
- Step 3: Test the Sensor Directly.
Does a V6 have two camshafts?
And a V6 engine has two heads. And two cam shafts for each head would give you four cam shafts like and follow for more videos like this.
How many camshaft sensors does a 6 cylinder have?
2 units
These sensors may be generally located at the front or rear areas of the related camshaft. The BF/FG 6 cyl utilises 2 units at the rear of the cylinder head area. One for the inlet camshaft. One for the exhaust camshaft.
