What Are Peugeot 308 Oxygen Sensors?
Oxygen sensors, or lambdas, sit in the exhaust and report air-fuel ratio back to the ECU for fine fuel-trim control. On Peugeot 308, 207 and 3008 petrols we see the upstream sensor lose accuracy after 100,000km, triggering poor economy and rough idle.

Common Questions About Peugeot 308 Oxygen Sensors
What are the symptoms of a bad Peugeot oxygen sensor?
Fuel use climbs, the check-engine light comes on, and the idle turns rough. Black exhaust smoke and a rotten-egg smell confirm a sensor giving the ECU bad readings. A proper scan reads the exact lambda value to confirm.
How much does it cost to replace a Peugeot oxygen sensor?
Through SA suppliers like Mr Sensors in Pretoria, Modern Auto Parts Bosch sensors, Masterparts, AutoMarine and AfricaBoyz, lambda sensors run R1,200-R3,500. Fitted at an indie, add R500-R1,000 labour. Get a free quote with your engine code.
Can I drive my Peugeot with a bad O2 sensor?
Short trips yes, long term no. The ECU defaults to a rich open-loop map that pours fuel into the cat. Extended driving in that state destroys a catalytic converter worth R15,000 or more. Fix it sooner, not later.
How long do Peugeot lambda sensors last?
OEM oxygen sensors on 207, 307, 308 and 3008 petrols typically last 100,000-150,000km. Cheap aftermarket units fail inside two years. Bosch or Denso replacements match OEM life. Always swap both pre and post-cat sensors together.
