Oxygen sensor Lambda sensor for Land Rover Upper oxygen O2 sensor
LR116639
Product Description:
Oxygen sensor
OE NO.: LR116639 LR142730
Applicable vehicle type: For Land Rover
The automotive oxygen sensor (O₂ Sensor) serves as the core
feedback component for engine emissions and closed-loop fuel
control. Positioned within the exhaust manifold (either upstream or
downstream of the three-way catalytic converter), it monitors
exhaust oxygen levels and outputs electrical signals. These signals
enable the ECU to precisely regulate the air-fuel ratio, ensuring
optimal power delivery, fuel efficiency, and compliance with
emissions standards. Oxygen sensors are categorised into
switch-type and wideband variants, accommodating different engine
technologies.
Signal Abnormalities
Idle vibration, increased fuel consumption, excessive emissions,
malfunction indicator illuminated
Clean sensor, measure heating resistor (normal range 4-40Ω),
replace heater; repair wiring harness/connector
Sensor poisoning
Signal drift, reduced catalytic converter efficiency, exhaust odour
Replace oxygen sensor directly; avoid using substandard fuel or
harmful sealants
Ceramic damage
No signal output, abnormal exhaust noise
Replace with identical model sensor; handle with care during
installation
Heating failure
Cold start closed-loop delay, high fuel consumption, fault codes
Measure heating resistance; repair wiring before replacing sensor
