Q: 2009 Nissan Murano won't pass smog check

The camshaft position error is a likely cause for the vehicle no-start situation. The engine computer reads and relies on camshaft and crankshaft angle readings for ignition timing. No angle reading, no spark and a fail-safe to prevent engine damage. This will likely illuminate the Service Engine Soon light not long before a failure. Have a trained mechanic, like the ones here at YourMechanic, inspect and adjust your camshaft’s position.
