Message	the CEL at least 5 times in 10 seconds at 2000 rpm the voltage variation may still be not be OK. For example a good O2 signal will usually yield about 0.9v at the high and about 0.1 v at the low to average out to about 0.5v. If the voltage variations are closer to the average (0.5v) like 0.6v high and 0.4v low the O2 is weak and should be replaced. If one of the O2 is weak and the other strong I would replace both. Use OEM units. When checking voltages only use a digital multi meter. Consult provides the voltages as a readout. ZUL8TR in Orlando,FL

Its like checking - NobleZ 10:55:13 12/17/09 just tested them and... - pearlzed 11:08:29 12/17/09 I would say yes. if they are 50,000+ miles old, the car will - NobleZ 11:15:29 12/17/09 now which ones? :s - pearlzed 11:17:51 12/17/09 Bosch or OEM nissan. some NTK O2s are actually Bosch - NobleZ 11:28:12 12/17/09 this is what i found for NGK - pearlzed 11:44:42 12/17/09 It's your call, but most will recommend OEM Nissan. (n/m) - marklar182 11:28:14 12/17/09 IIRC - NytWolf 11:31:27 12/17/09 thanks yea i did make sure of that! - pearlzed 11:46:01 12/17/09 Something else on checking O2s. Even if they blink >>> - ZUL8TR 12:24:49 12/17/09 yeah i am replacing them both - pearlzed 12:42:09 12/17/09
