if i got the primary o2 sensor and missing the secondary one, will it effect my performance in any way?? i read that the primary sensor is use by the compter to adjust fuel and the secondary is use to chech the cat performace, so is this true?? i juts realize my car is missing the secondary 02 sensor and just wondering if it will efffect performance of my car such as V-Tec engagment and so on. thank for the help all

 

no it will not affect your car's performance... relax, your "V-Tec" is fine. Your car doesnt happen to be 95 or older does it? Because then it would be normal to have only 1 o2 sensor..

 

well good to know my "V-TEC" power is fine. thank for the help. I gonna sleep well now knowing my "V-Tec" is not being effected by the O2 sensor. thank again for the help.
