AIR BAG SENSOR FOR FRENCH MANUFACTURED VERSION OF 2005 YARIS T3

[CTScott]

B1140 indicates a malfunction of the right side sensor. It could be the wiring between the SRS ECU and the sensor, but is more likely the sensor itself.

Try cheaptoyotaparts.co.uk. I have found them to be reasonable for some European Yaris parts that I ordered and had shipped to the US.

Hi,

Thanks for the information. Just to clarify what you mean by the right side sensor. The car is used on British roads, where we drive on the left side of the road. The driver side is the right side (nearest the centre of the road), when looking at the vehicle from the back, and the passenger side is on the left (nearest the side of the road). Sorry if this seems as if I am being sarcastic - I am not, but need to be certain before I buy a replacement.

My reason for making certain that we are talking about which side sensor is because I have been told B1140 refers to the passenger side of the car.

Hope this is clear, and, once again, I do very much appreciate your help.

Regards

Ed

According to the service manual it is the right side (they are described as right and left, as opposed to driver and passenger), which in your case would be the driver's side. Looking at the electronic parts catalog, the LHD and RHD French made Yaris share the same part number for the same side (so, whether RHD or LHD, the right side sensor is 89835-52010).

There is a difference in the sensors as the part number for the left side is: 89865-52010

Hi,

I have looked at the part numbers of the actual units that are fitted. The right side door sensor is marked 89865-52010 with the letters RH prominent (the opposite of your last sentence above). The left side door sensor is marked 89835-52010.

Would you agree that in accord with B1140 I should be looking for a replacement for 89865-52010?

Thanks for your understanding and patience in this matter.

You are correct. When I pasted the part numbers above I transposed them.

The EPC lists (for both LHD and RHD 01-05 Yaris):

89865-52010 as Sensor, door side air bag, RH
89835-52010 as Sensor, door side air bag, LH


The easiest way to be absolutely sure is to unplug the RH sensor and then read the DTCs again. If you have the correct sensor unplugged you should still only see B1140. If you have the incorrect one unplugged then you will have a second DTC.
