Walker Products Oxygen Sensor P/N:250-54106

Keep the air-fuel feedback loop reporting accurately with the Walker Products Oxygen Sensor 250-54106, a 4-wire wide-band air/fuel ratio sensor that installs as a direct-fit replacement for the 1997-1999 Toyota Camry (L4-2.2L) and the 1999 Toyota Solara (L4-2.2L).

An oxygen sensor measures the oxygen content of the exhaust gas so the ECU can monitor the air-fuel ratio for combustion efficiency. As a wide-band design, it reads a broader span of air-fuel ratios than a conventional narrow-band sensor. If a failed oxygen sensor is the cause of poor running, increased fuel consumption, higher emissions, or an illuminated malfunction indicator lamp (MIL), this Walker unit replaces it — diagnose the fault code before replacing, since the wiring harness and connector should also be checked for physical damage.

• Wide-band air/fuel ratio sensor: heated, 4-wire construction for the diagnostic feedback the ECU requires.
• Platinum electrode: a gas-permeable platinum layer, coated to resist contamination and erosion from combustion residue and exhaust particulates.
• Threaded mounting: four spade terminals in an oblong connector, with a 22 mm wrench size.
• Specific-fit application: built for the listed vehicle and sensor position.
