- Incorrect air-fuel feedback from a worn heated sensor
- Slow sensor response after extended mileage
- Emissions test failures tied to rear sensor readings
- Connector or fitment mismatch on the specified Saab, Saturn, or Volvo application
Installation Notes
Confirm the vehicle position before ordering, since this sensor is listed for rear, rear left, and rear right locations depending on application. Verify the 4-wire flat connector, 18 x 1.5 mm thread size, and overall length of 1045.0 against the original sensor before installation. Use the included instruction sheet and follow the vehicle service procedure for safe removal and replacement.
Quality Assurance
Delphi builds aftermarket parts with OE experience and supplier knowledge drawn from its work with leading automakers. That OE background is reflected in the ES20115 sensor design and application-specific fitment.
