Hi

I have a 335 with procede v2 installed and from time to time (with increasing frequency) I get P0237 (Turbocharger Boost Sensor A Circuit Low) code at cold start.

Did anyone have that?

Thanks

Check mthe TMAP connection in te ECU box. It will be the green loom. Just make sure it is properly seated.

Guys, I just got this code (P0237) along with P142E. Reading above, I dont see a GREEN LOOM in the ECU box. Do I not have one on the 2008 e90?

Thanks and any other suggestions on what caused this?

That makes sense then. The green loom reference was to a PROcede installation. Check the connection on the Large Black sub-assembly, terminal 10.

The JB3 processor subassy or one of the black ecu connectors (and which one)?

Thanks, I appreciate the help.

Check both of them.....the JB3 connector and the stock harness as well. The larger black subconnector.

Like Scalbert indicates, find slot #10 and see that the pins are properly seated in the slot and that the male and female terminals are making good contact.

When you insert the pins into the slot, there is a click and lock. If you look at the metal pin you will see a small rectangle on the surface that acts as a locking mechanism once the pin is inserted into it's proper slot in the plastic connector. You should inspect these rectangles to make sure they are correctly locked in place in the plastic connectors.....both JB and stock.
