The Honda CR-V uses a single camshaft position sensor. The inline-4 engines common to CR-V models throughout the lineup rely on one camshaft position sensor (CMP) to monitor cam timing, and they use a separate crankshaft position sensor (CKP) for overall timing synchronization.
Understanding this helps when diagnosing timing, misfire, or startup issues. While some Honda engines with multiple banks can use more than one CMP, the CR-V’s four-cylinder configurations do not require a second camshaft sensor in standard production.
What a camshaft position sensor does
The camshaft position sensor tracks the angle of the camshaft to inform the engine control module when to fire the ignition and inject fuel. In CR-V inline-4 engines, this single CMP works in concert with the crankshaft position sensor to coordinate timing across the engine’s cycles.
CR-V camshaft sensor count across generations
The CR-V’s four-cylinder engines are DOHC and traditionally use one camshaft position sensor. There are no standard CR-V configurations with two CMP sensors. A separate crankshaft position sensor remains part of the timing system to provide additional reference points for engine timing.
- Single camshaft position sensor for CR-V inline-4 engines.
- Crankshaft position sensor is a separate sensor, used together with the CMP.
- Some Honda models with multi-bank configurations may use two CMP sensors, but this does not apply to the typical CR-V lineup.
For diagnostic purposes, expect one CMP and one CKP on most CR-V engines when troubleshooting timing-related codes.
Practical implications for maintenance and diagnostics
If a CMP fails or shows a fault, symptoms can include misfires, rough idle, poor starting, or a check engine light with CMP-related codes. Replacing a CMP usually involves accessing the timing cover or cylinder head and must be done with proper torque specs and timing alignment per Honda service procedures.
Summary
Across Honda CR-V generations, the engine architecture relies on a single camshaft position sensor paired with a crankshaft position sensor. This configuration has remained consistent despite changes in engine design over the years, making CMP-related diagnostics more straightforward for CR-V owners and technicians.
