The Bank 2 camshaft position sensor is typically located on the camshaft in the cylinder head of the opposite bank from Bank 1. Some engines do not have a Bank 2 sensor at all, so always check your specific vehicle’s service manual for the exact location.
Bank 2 refers to the second bank of cylinders in a V- or flat engine layout. The camshaft position sensor (CMP) monitors the position of the camshaft to help the engine control module time fuel injection and ignition. Locations vary by manufacturer and engine design, and some engines use a single sensor instead of a Bank 2 sensor.
Understanding Bank 2 and sensor locations
In a V-shaped engine, the cylinders are arranged in two banks. Bank 1 contains the cylinder with the first cylinder number, while Bank 2 is the opposite bank. The CMP is mounted either directly to the camshaft or to the nearby camshaft cover in each bank. Access can be from the top of the engine, the side, or sometimes behind exhaust components, depending on the model.
Common locations by engine design
The following guidelines cover typical placements for Bank 2 camshaft position sensors across common layouts. Note that exact placement can vary by make and model.
- DOHC V-series engines (V6, V8, V10, etc.): Bank 2 CMP is mounted to the cylinder head on the opposite bank from Bank 1, near the camshaft. The electrical connector is usually a two- or three-pin plug and may be near the timing cover or behind an intake/valve cover area.
- Inline engines (I-4, I-6, etc.): These engines usually have a single camshaft position sensor. In such cases, there is no Bank 2 sensor to locate.
- Dual-cam-per-bank configurations: Each bank may have its own CMP on the corresponding head. Bank 2’s sensor will be on the Bank 2 head, adjacent to the camshaft and timing components.
In practice, if you know which bank is Bank 1 (for example, the bank containing cylinder 1), Bank 2 will be the opposite bank. The sensor is typically mounted to the head, timing cover, or in rare cases behind ancillary components, and you’ll usually see a multi-pin electrical connector attached to it.
Locating Bank 2 CMP on your vehicle: practical steps
To pinpoint the Bank 2 CMP on a specific model, use these practical steps. This approach works whether you’re diagnosing a fault or just trying to inspect the sensor.
- Identify whether your engine is a V-type or inline configuration and determine which bank is Bank 1 (usually the side containing cylinder 1).
- Consult the vehicle’s service manual or factory diagrams for the exact sensor location. If you don’t have a manual, search the make/model/year along with “camshaft position sensor Bank 2 location.”
- Open the engine bay and visually inspect both cylinder-head areas around the timing cover for a camshaft position sensor with an electrical connector.
- Look for a sensor mounted near the camshaft gear or chain/tollowing area, often along the edge of the head or near the back of the timing cover.
- Confirm by tracing the wiring harness: CMP connectors are typically small, with two or three pins, and run to the engine control module or wiring harness routing near the engine bay.
If you still can’t locate it, consider checking aftermarket repair databases, forums for your vehicle, or asking a dealership/service department with your VIN handy for the exact diagram.
Summary
Bank 2 CMP location depends on engine layout and manufacturer. On DOHC V engines, it’s usually on the Bank 2 cylinder-head side opposite Bank 1, near the camshaft and timing components. Inline engines often lack a Bank 2 sensor, while some engines place a CMP on each bank. Always consult the specific service manual for your vehicle to confirm the exact location and access points.
