Walker Products 250-23060 oxygen sensor for the 1988-1991 Porsche 928 V8 5.0L and other vehicles measures the oxygen content of the exhaust gas. Each Walker part number is made for one specific application and fitment position, so the ECU gets the diagnostic feedback it expects.
- Measures exhaust oxygen to help fine-tune the air-fuel mixture and fuel economy
- Monitors the air-fuel ratio to show combustion efficiency
- Monitors exhaust gases to help reduce pollutants
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 250-23060 oxygen sensor
- Fits: 1988-1991 Porsche 928 V8 5.0L and other vehicles
- Position: Upstream
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a malfunction indicator light. A damaged wiring harness or connector can be behind those signs too, so trace the cause before you buy a sensor. This listing is one upstream sensor, and the car needs one in that position.
