Oxygen Sensor Module, Power. Our gauge kit will come with an OEM 4. Wideband O2 Systems. Follow the turbo crossover pipe from the exhaust header to where it runs up by the lower control arms. Generally, if we are talking about O2 sensors: Sensor 1 = Before Catalytic converter Front (Upstream O2 sensor) Sensor 2. Huge discounts on Phillips Respironics Wisp Lnasal. To understand why an exhaust leak is so detrimental to O2 sensor (also known as a wideband sensor) performance, one must first understand how an O2 sensor works. I warmed it up with just the o2 plug in, then put the wideband in. Please review our privacy policy & cookies information page. O2 sensor voltage = what A/F ratio? Forced Induction (Turbo/S. But as for his "test", I would give him an F. This thing has enabled me to do some pretty specific carb tuning. They don't last forever, and many different factors can cause them to fail earlier than others. Mount the wideband oxygen sensor before the catalytic converter and at least 24 inches downstream from your engine block or turbo for optimal performance. That's why they're used on every dyno.
