KISS Diagnostics Oxygen (O2) Sensors Pack: 26 Diagnostic Cheat Sheets (HTML + Printer-Friendly PDF)

O2 sensor codes get blamed on the sensor far more often than the sensor is the problem. 26 cheat sheets that cover every sensor position, circuit, response, heater and signal fault, so you can tell a failing sensor from an exhaust leak, a fuel trim problem or a wiring fault. Every sheet includes a waveform reference. Written by a licensed technician with 2o plus years in the bay.
