Defender Td5 Engine Sensors

Defender Td5 engine sensors for fault-finding, routine replacement and common running issues on Land Rover Defender Td5 models. This section includes crank sensors, MAP sensors, MAF sensors, AAP sensors, coolant temperature sensors, oil pressure switches and related Td5 engine sensor parts.

Use this page when you are replacing a known faulty sensor or working through a Td5 running, starting or signal-related fault. Crank sensors are commonly linked with starting and cutting-out faults, while MAP, MAF and AAP sensors are used by the engine management system for air, boost and load-related readings.

• Standard replacement sensors: use these when replacing failed or suspect original Td5 sensors.
• Boost and air-reading sensors: MAP, MAF and AAP sensors can affect running, smoke, power delivery and fault-code diagnosis.
• Temperature and pressure switches: coolant temperature sensors and oil pressure switches support basic engine monitoring and warning systems.
• Uprated sensor options: for tuned or modified Td5 vehicles, see uprated Td5 sensors.

Many Td5 engine sensors are shared between Defender Td5 and Discovery 2 Td5, but always check the individual product page for part number, brand and fitment notes before ordering.
