TD5 Crank Position Sensor Overlay Harness – Defender & Discovery 2
The TD5’s crankshaft position sensor is critical for accurate engine timing and reliable starting. As these vehicles age, the original sensor wiring is known to become brittle, heat-soaked and prone to internal breaks or interference. This can lead to classic TD5 symptoms such as intermittent non-start, cutting out, rough running or inconsistent performance – often without a clear fault code.
This overlay harness provides a direct, high-quality replacement route that bypasses the ageing factory wiring. Manufactured using screened automotive-grade cable, upgraded insulation and durable protective sleeving, it offers a long-term fix for one of the most common electrical gremlins on TD5 engines.
Key Features
- Restores reliable crank sensor signal by bypassing damaged or degraded OE wiring
- High-spec screened cable reduces electrical interference and improves signal stability
- Improved heat and vibration resistance compared to the factory loom
- Plug-and-play style overlay – no complex rewiring of the main harness
- Suitable for Defender TD5 & Discovery 2 TD5 (non-ABS and ABS)
- Helps resolve hot start issues, intermittent engine cut-outs and difficult cold starts
Ideal For
- Vehicles suffering from intermittent crank sensor faults
- High-mileage TD5 engines where wiring degradation is common
- Preventative maintenance before off-roading or long trips
A simple but highly effective upgrade that quickly pays for itself by eliminating one of the TD5’s most frustrating and time-consuming faults.
