Notes
The sensor contains a ceramic module and should not be subject to mechanical or
thermal shock or it may be damaged. The sensor is not designed for operation on
leaded fuels, doing so will dramatically shorten sensor life. Long term running in the rich
region (Lambda < 0.95) will shorten sensor life. High exhaust temperatures (over 850C)
will shorten sensor life. Engine oil consumption at a rate greater than 1 quart per 1,000
miles will shorten sensor life. With the UEGO Sensor installed, do not run the engine
without power applied to the gauge.
