P1519 on 1999-2002 Mercury Cougar — Intake Camshaft Control / Adjustment Bank 1 Malfunction
1 vehicles · 1 makes · $120-$600 repair
Most Reported On
P1519 is an OBD-II diagnostic trouble code meaning “Intake Camshaft Control / Adjustment Bank 1 Malfunction.” P1519 is a manufacturer-specific code most commonly found on VAG vehicles (Volkswagen/Audi), where it indicates a malfunction in the intake camshaft control (variable valve timing / camshaft adjustment) on Bank 1. The engine control module has detected that the intake camshaft cannot be adjusted to the commanded position, meaning the VVT system on that bank is not responding correctly. On some other makes the same code number is used differently (e.g., BMW: inlet camshaft end-position plausibility; Mercedes-Benz: camshaft position control mechanical fault; some others: intake manifold runner control stuck closed), so the exact meaning can vary by manufacturer. This code is most commonly reported on 1999-2002 Mercury Cougar, with repair costs ranging from $120 to $600.
