Q: What does code P1336 mean?

Crankshaft Camshaft Sensor Range Performance. P1336 on a Jaguar indicates the engine control module (ECM) has detected a performance range problem between the crankshaft position sensor and the camshaft position sensor signals. The ECM compares the two signals during engine operation and flags this code when their relative timing or correlation falls outside the expected range, which can affect fuel injection and ignition timing.

Symptoms you may notice

Illuminated check engine light, often with no other noticeable symptoms
Intermittent engine misfire or rough running, especially under load
Difficulty starting or extended cranking before the engine catches
Reduced engine power or limp mode activation in some cases
Poor fuel economy or increased emissions
Occasional stalling when coming to a stop or at idle

Common causes, most likely first

Worn or stretched timing chain, particularly on Jaguar V8 engines known for timing chain guide failure
Faulty crankshaft position sensor or damaged reluctor ring
Faulty camshaft position sensor or contaminated sensor tip
Wiring harness damage or corroded connectors between the sensors and the ECM
Oil sludge or debris interfering with sensor signal pickup
ECM software calibration issue requiring a reflash or update

How to diagnose and fix it

Perform a visual inspection of the crankshaft and camshaft sensor connectors and wiring for chafing, corrosion, or loose pins
Use a scan tool to check for other stored codes and freeze-frame data to confirm the fault conditions
Verify sensor signals with an oscilloscope to compare crankshaft and camshaft waveforms for timing correlation
Check the timing chain for stretch or guide wear by inspecting the chain tensioner and timing marks
Test the crankshaft and camshaft position sensors for resistance and signal output according to Jaguar specifications
Repair or replace damaged wiring or connectors as needed
If all else checks out, update the ECM calibration or replace the ECM only after confirming sensor and timing integrity

Timing chain wear often mimics sensor failure

On many Jaguar V8 engines, a P1336 is the first warning of a failing timing chain tensioner, and replacing sensors alone will not fix the underlying mechanical wear.
The code can be set by a dirty or contaminated camshaft sensor tip picking up metallic debris, which is often overlooked during diagnosis.
A weak battery or poor ground connection can cause voltage spikes that disrupt sensor signals and trigger P1336 without any faulty component.
After replacing a sensor or repairing timing components, the ECM may require a relearn procedure or a drive cycle before the code clears permanently.
P1336 can be stored alongside misfire codes, leading some to replace ignition coils unnecessarily when the root cause is timing correlation.

Can I keep driving with P1336?

You can drive the vehicle short distances to a repair shop, but avoid heavy acceleration or sustained high speeds because the fault can cause misfires and potential engine damage. If the engine runs rough or stalls frequently, stop driving and arrange a tow.
