06 S60 Brake Pedal Position Sensor going bad after 6 months? Topic is solved

Hi Everyone,

Six months ago I changed my Brake Pedal Position sensor (https://www.ipdusa.com/products/16513/1 ... ion-sensor) because it was leaking and started to give me ECM-900C code once in a while.

Is it possible that the unit is broken again or is my BCM going bad? Is there any other way to test it then getting a new sensor? This is my daily driver..

Here are ViDA graphs:
All the codes:

Details for ECM-900C:

Details for BCM-0147:

Here is a graph from BCM of the position sensor. After about 40s the values froze but I'm not sure if it was because ViDA disconnected or because of the sensor. I might repeat this again.

Thanks for your input!

Remove the electrical connector and inspect for any corrosion and for female terminal tension. You can use a paper clip and hammer it to flatten it to be the same approximate thickness as pins in the sensor and then insert it into connector and see if falls out on its own and also if there is felt drag is you try to pull it out. Usually a comparative test can be made on any multiple terminal connector as they will usually not all have the problem.
If all is oK there then it could just be a bad part, it happens.

Quality: aftermarket

Get a used genuine one off ebay & make sure its secured properly in place with the circlip

Sorry for such long break. I had to do PCV system and didn't have time to get to this.

It looks like jimmy57 was right. I cleaned the terminals and everything looks good. The cruise was disabled on most of my drives before but it's been working good for the past week. I'm a professor so let's see if it's going to last through this coming semester.
