50% of the emissions from late-model vehicles are due to malfunctions.

A smoothly running engine not only saves money, it also helps save the environment. Your car’s check engine light comes on whenever emissions exceed 1½ times the federal standards for that model-year.

But don’t wait for the check engine light to come on. When there’s a malfunction in your car’s sensors, the engine burns more gas and exhausts more pollutants. With CarChipE/X, you can keep an eye on selected engine parameters—so you’ll always know whether or not your car is running cleanly.

For example, you can tell how efficient your catalytic converter is by keeping an eye on oxygen sensor voltage. Replacing a bad converter can reduce hydrocarbon emissions by 33% or more.

After repeated failed smog checks, David replaced his oxygen sensor—again! Too bad David didn’t have CarChip. He would have known about the faulty sensor sooner, saving hundreds of dollars in unnecessary repairs.
