Boost Pressure Sensor 1Z

Hello everyone,

I have a question that someone might be able to answer. I purchased an external pressure sensor (300 kPa) from the shop.

Okay, here's the translation:

'Now my question: Do I need to completely desolder the old sensor from the control unit, or can I directly connect the cables from the external sensor to the corresponding connectors?'

Hello,

It will then have aged well for a year.

According to the included pinout diagram, 3 of the connectors instead of the original boost pressure sensor can be directly connected to the control unit (ground, +5V, signal voltage).

It's easiest to use the original charge air temperature sensor and not the one integrated into the external sensor.

Warning: The engine control unit (ECU) software needs to be adjusted to match the other sensor, and that's a job for your tuner.

Well, he should actually know how to connect the sensor...

Best regards, Rainer.

Hello,

Thank you for the quick response. Yes, it took a little while for me to finish the box.

'I've been using the integrated charge air temperature sensor for a while now, and it's working perfectly. Since I have a completely new piping system, I didn't want to install two connections if I could also do it through the combination sensor from you. I haven't had any problems with it, so I think the temperature values that the Bosch computer is displaying are plausible. In your opinion, what would be the advantage of keeping the old sensor? Or what would be the disadvantage of the new one?'

Hi,

Well, now that we've established that nothing needs to be changed? Unfortunately, the input values are not always the same.

Best regards, Rainer.

Yes, you're right. But as I said, it's already in use and it's also working.
I will be commissioning the pressure sensor within the next 14 days and will give you a brief update on whether everything worked as expected.

Thank you.

Best regards, Hansi.
