It's reading rich. The output of the sensor is a roughly "S" shaped curve with the middle range - right around .5 volts - being *very* steep. Looking at the output of a working O2 sensor on a properly-tuned engine you'll typically see very rapid fluctuations above and below the .5 volt output. --------------------------------------------------------------- Tom Young '81 Vanagon Lafayette, CA 94549 '82 Westfalia --------------------------------------------------------------- ----- Original Message ----- From: "Jeff Hammerstrom" <speakerdesign@MSN.COM> To: <vanagon@GERRY.VANAGON.COM> Sent: Sunday, July 13, 2003 3:05 PM Subject: O2 sensor output voltage test
