Chevrolet Cavalier Gas Mass Sensor

$500 + $200 Core Charge

Rebuilt gas mass sensors with a 90-day warranty. These should work with all 1998-2002 Chevrolet Cavalier bi-fuel CNG cars.

Bring us your rebuildable gas mass sensor and we will give you a rebuilt unit for $500 or you can buy a rebuilt one for $700 without giving us your core. We can also install the gas mass sensor for you for $75 with an appointment.

Typically, if the car is not running on CNG and you have a check engine light showing code P1202, you most likely need to have the Gas Mass Sensor rebuilt. We recommend that you have a mechanic diagnose your problem as the gas mass sensor before replacing it.

Call 801-802-6080 or email cngutah@gmail.com to purchase or if you have any questions.
