What it means

On a Jaguar, P1341 is read as Camshaft Position Sensor B Circuit Range/Performance. The engine control module has seen a signal from the second camshaft sensor that is implausible or out of step with the crankshaft position signal. This points to a problem with the sensor, its wiring, or the camshaft timing and trigger wheel. Which camshaft the 'B' sensor monitors depends on the engine, so confirm this for the specific model.

Symptoms

Malfunction indicator lamp on
Long cranking or hard starting
Rough running or hesitation
Reduced power, possibly with the engine in a limited performance mode
Intermittent stalling
Poor fuel economy

Possible causes

How to diagnose

Read all stored and pending codes and note freeze frame data, looking for related camshaft, crankshaft or variable valve timing codes.
Check engine oil level and condition, as poor oil can affect valve timing components and leave debris on the sensor.
Inspect the camshaft sensor B, its connector and wiring for damage, oil contamination, chafing, corrosion or loose pins.
Check the sensor mounting and air gap, and inspect the sensor tip for debris or damage.
Check the sensor's supply, earth and signal circuits for continuity, shorts and voltage drop, following the model-specific wiring diagram.
View live camshaft and crankshaft signal data, or use a scope to compare the two waveforms for dropouts or noise.
Check the variable valve timing operation and the cam-to-crank timing correlation, using live data or a timing inspection as the model requires.
If timing correlation is wrong, inspect the timing chain, tensioners and guides, following the manufacturer procedure for the engine.

How to fix

Replace the camshaft position sensor B if it tests faulty or is contaminated.
Repair or replace damaged wiring, and clean or replace corroded or loose connector terminals.
Correct the camshaft timing by replacing worn chain, tensioner or guides, and retime to specification.
Repair or replace the variable valve timing actuator or control valve if it is faulty or sticking.
Replace a damaged trigger wheel or reluctor.
Diagnose and replace the control module only after all other causes are ruled out and the manufacturer procedure confirms the fault.

Can I keep driving?

Medium severity

Short, careful trips may be possible, but the engine could stall or run poorly. If the cause is a timing fault, continued driving risks serious engine damage, so get it checked soon.
