I have 1 of these wideband guage setups , and it seems the o2 sensors go bad every year . My question is this , since the earlier civics came with Bosh wideband O2 sensors , could i just get a replacement Bosh O2 sensor for one of those earlier civics ( don't remember what year civic) and replace the AEM 02 sensor when ever it goes bad ?

 

No you can't use a Bosch replacement. Stock O2 sensors are narrowband (0-1V) and will not work with wideband gauge (0-5V).

 

thanks for the reply

 

just got off the phone with bosch , the O2 sensor is used in the Caddys specifically the CTS and the STS , part# Bosch 17205 .
