APPLICATION: Vortec Engine applications with Drive by Wire Throttle Body NOTES: These Oxygen Sensors are used on PSI Drive by Wire Vortec harnesses HAR-1014, HAR-1015, and on PSI LS2 Harnesses HAR-1094, HAR-1095. They are also used in many OEM applications. Oxygen Sensors (O2's), are one of the most important parts of an LSX Swap. They relay the Air Fuel Ratio back to the ECM so your engine runs Optimally. O2 Sensors are a Wear Item, just like a spark plug or serpentine belt. O2 Sensors that are high mileage, have been submerged in water, have been removed from a junkyard with a torch, or are in any other way damaged, should be replaced. PSI Wiring Harnesses are Designed to use a Specific O2 Sensor, usually based on engine generation.
