UEGO Sensor Mounting
A weld-in UEGO bung is supplied for sensor installation. Mount the UEGO sensor in the exhaust system at least 18 inches downstream from the exhaust port. If you anticipate high EGT's (over 800C), run a turbocharger, run at high RPM for extended periods of time or plan on running leaded race fuel then you must mount the sensor at least 36 inches or more downstream of the exhaust port as all of these can cause the sensor to overheat. On turbocharged engines the UEGO sensor must be installed after the turbo charger, if not, the pressure differential will greatly affect the accuracy of the unit. For accurate readings, the sensor must be mounted before catalytic converters and/or auxiliary air pumps. To prevent collection of liquids between the sensor housing and sensor element during the cold start phase, the installation angle should be inclined at least 10° from horizontal with the electrical connection upwards, see Figure 2.

Indicator Lights
The Inline Wideband UEGO Controller has two indicator lights, see Figure 4. Both the ready light and the status light flash during sensor warm up. Once the sensor reaches operating temperature, usually within 30 seconds, the status light will turn off and the ready light will remain on solid. During sensor warm up, AFR readings may not be accurate. The status light will also flash if a sensor error is detected. The status light will flash on and off a number of times, followed by a short pause. The error codes are listed below in Table 1.
