Service Information

We recommend replacing genuine DENSO oxygen sensor or fuel pump with OE-grade replacement products made for aftermarket use by DENSO. Please contact our Distributors for stockist information.

Replacement of oxygen sensors should be part of every vehicle’s scheduled maintenance. DENSO recommends changing oxygen sensors with every tune-up as well as any other time there is a risk of oil, lead additives, coolant or water entering into the exhaust system. In these circumstances the oxygen sensor(s) should be changed to rule out the possible sensor contamination.
