P0130 on Peugeot by model: symptoms, diagnosis and fix
A very common 206 complaint on multiplexed cars is the 'Anti-pollution fault' message on the multifunction display, often accompanied by the engine management light, misfire, lost power or limp mode. It is a generic emissions-system alert triggered by a range of root causes documented across owner forums: failing ignition coils, lambda (oxygen) sensor faults, sticking EGR valves, sticky hydraulic tappets and, on neglected cars, catalytic converters damaged by sustained misfiring. Because the message is generic, owners frequently replace the wrong parts before reading the stored fault codes.
Common Symptoms
- 'Anti-pollution fault' message on the multifunction display
- Engine management light on
- Misfire or juddering, especially under load
- Loss of power or limp mode
- Engine cutting out shortly after the warning appears
How to Fix
Read the stored DTCs with PSA-capable diagnostics rather than guessing; the accepted fixes are replacing the specific failed component — most commonly an ignition coil pack or lambda sensor, cleaning or replacing the EGR valve, or replacing a misfire-damaged catalytic converter in advanced cases.

Frequently asked questions
What does P0130 mean on a Peugeot?
P0130 stands for "O2 Sensor Circuit Malfunction (Bank 1, Sensor 1)." This code indicates a malfunction in the upstream oxygen sensor circuit for bank 1, sensor 1 — the front O2 (or air-fuel ratio) sensor mounted before the catalytic converter on the side of the engine containing cylinder 1. This sensor measures the oxygen content of the exhaust so the computer can fine-tune the fuel mixture, and the code sets when its signal is missing, out of range, implausible, or not switching as expected. A faulty reading here can hurt fuel economy, increase emissions, and trigger the check engine light. It generally points to the sensor itself, its heater or wiring, or sometimes an exhaust/fuel condition the sensor is reporting. On Peugeot it is documented across 1 model: 206.
What are the most common causes of P0130?
The most common causes of P0130 are: Failed or aged upstream oxygen / air-fuel ratio sensor, Damaged O2 sensor wiring, connector, or heater circuit, Exhaust leak near the sensor, Blown fuse or open in the sensor heater power supply, Corrosion or poor contact at the sensor connector, Vacuum leak skewing the fuel mixture, Contaminated sensor (oil, coolant, or silicone). The specific cause varies by vehicle.
How much does it cost to fix P0130 on a Peugeot?
Published repair estimates on Peugeot range from $100 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
