What is a code B1009

Question edited for clarity.

Be careful with terminology, ATF Fluid is a sort of an oil, but it is light in viscosity. Gearbox oil is for vehicles with manual transmission and is considerably thicker and would cause issues in an automatic.

This means your oxygen sensor is reading problems with your fuel/air mixture. May consider in replacing the oxygen sensor, the one before the catalytic converter.

You need to identify the year/model and engine.

If the code says component is slipping then you have a worn clutch pack or low trans oil pressure

Hi,
The only option you have is to contact the Mazda Dealer. Give them the Chassis number etc, from this they will be able to give you the factory security code for the antitheft alarm.
All Mazda Dealers have access to this database but only when given specific information which is on the ID plate in your vehicle.
Hope this helps. Let me know how you get on.

Hi
Code 26 is the clockspring under the centre of the steering wheel, you may have problems with your cruise control and horn as well. It will most prob need replacing, could be a diy job but bear in mind the previous threads caution.
