1 vehicles · 1 makes · $600-$2,500 repair
Most Reported On
P1396 is an OBD-II diagnostic trouble code meaning “Variable Valve Timing Solenoid Malfunction — Bank B.” Jaguar manufacturer-specific code for the variable valve timing system on the AJ-series V8. The ECM commands the VVT solenoid on the 'B' bank and monitors the resulting camshaft position; P1396 sets when the commanded valve-timing change is not achieved, indicating a fault in the VVT solenoid, its circuit, or the mechanical phasing it controls. Jaguar publishes a dedicated diagnostic procedure ('Variable Valve Timing Solenoid - DTC P1396 Diagnosis') that checks the VVT solenoid, the VVT actuator and the camshaft position sensor reluctor. The companion code P1384 covers the 'A' bank. This code is most commonly reported on 2007-2009 Jaguar XK (XK, XKR), with repair costs ranging from $600 to $2,500.
