P2135 on Jaguar
Throttle/Pedal Position Sensor Voltage Correlation
P2135 on Jaguar vehicles indicates throttle/pedal position sensor voltage correlation. Au7o has documented this code across 2 Jaguar models — most commonly on XJ, XK. P2135 means the powertrain computer detected that the two throttle position (TP) or accelerator pedal position sensors disagree with each other. Drive-by-wire systems use redundant sensors so the PCM can cross-check the throttle or pedal reading for safety; if the two signals don't correlate within an expected range, this code sets. As a fail-safe, the vehicle often enters a reduced-power 'limp' mode, causing sluggish acceleration, a stuck or hesitant throttle, and a warning light. Because it affects throttle control, it should be addressed promptly. Typical repair costs on Jaguar range from $200 to $900, depending on the specific model and root cause.
Common Causes of P2135
- •Faulty throttle position sensor / throttle body assembly
- •Faulty accelerator pedal position sensor
- •Damaged wiring or connectors at the throttle body or pedal
- •Corroded or loose connector terminals
- •Poor ground or reference voltage problem
- •Carbon buildup binding the electronic throttle plate
- •Failed PCM (rare)
P2135 on Jaguar by Model
Jaguar XJ(1 issue)
- Electronic Throttle Body Failure2004-2009
The electronic throttle body on the X350 XJ develops a sticky or erratic response due to carbon buildup and motor wear. The drive-by-wire throttle loses calibration, causing surging idle, hesitation on acceleration, and intermittent limp mode.
Jaguar XK(1 issue)
- Throttle Body Position Sensor Failure2007-2015
The electronic throttle body on the XK develops position sensor failures causing erratic throttle response, limp mode, and check engine lights. The dual-track position sensor wears internally, sending conflicting signals to the engine management system.

What does P2135 mean on Jaguar?▼
P2135 stands for "Throttle/Pedal Position Sensor Voltage Correlation." P2135 means the powertrain computer detected that the two throttle position (TP) or accelerator pedal position sensors disagree with each other. Drive-by-wire systems use redundant sensors so the PCM can cross-check the throttle or pedal reading for safety; if the two signals don't correlate within an expected range, this code sets. As a fail-safe, the vehicle often enters a reduced-power 'limp' mode, causing sluggish acceleration, a stuck or hesitant throttle, and a warning light. Because it affects throttle control, it should be addressed promptly. On Jaguar specifically, this code is documented across 2 models.
