Original BMW Fuel Tank Pressure-Temperature Sensor for BMW i3 and i3s Range Extender (2014–2021)

Built for Range Extender cars only, the Original BMW pressure-temperature sensor 16-14-7-426-661 monitors pressure and temperature in the fuel tank system of the BMW i3 and i3s. It is also known as a fuel tank pressure sensor. The sensor weighs 65 g, and BMW has produced it since July 2014. It appears as item 5 on its BMW parts diagram. On the i3, the Range Extender adds a small gasoline engine that charges the high-voltage battery on the move. That engine needs its own fuel tank, and this sensor belongs to that system, so all-electric cars without it have no use for the part.

Original BMW Parts carry a 24-month parts warranty.

This number supersedes the earlier 16-14-7-391-383. BMW rates the change as exchangeable retrospectively, which means the current sensor can go into cars that were built with the older number. BMW applies the part across both I01 generations: the early i3 Range Extender cars with the 60Ah and 94Ah batteries, and the facelifted cars, where the i3 and i3s Range Extender came with 94Ah and 120Ah batteries. Battery capacity does not change the sensor, so one part number covers all of these versions. The only real split is whether the car has the Range Extender. Each sensor is sold individually.

Common Questions

Will this sensor fit an i3 without the Range Extender?
No. BMW applies this sensor only to i3 and i3s cars equipped with the Range Extender.

My car has 16-14-7-391-383. Is this the replacement?
Yes. BMW superseded that number with 16-14-7-426-661 and rates the newer sensor as exchangeable retrospectively.

Does battery size change which sensor I need?
No. The same part number covers the 60Ah, 94Ah, and 120Ah Range Extender cars.
