Aloha,

I bought a spare BOSCH CPS.
The one side has a date code.
25 W14
Fourteenth week of 2025.

You also note that the cheap spare I had to carry around from an autoparts store has a smooth shaft (no jokes please) and no numbering.

The bosch part has two ribs that run down the shaft that can be felt and seen. ( again, please no jokes)

When I replaced.the original CPS (60k ago) with a Bosch I had a tough time fitting the Bosch with the ribs back into the hole when the engine was still hot so I sanded off the ribs, and walla it slipped right in.
Please don't say those are locating ribs or some other rubbish.As the bolt positions the sensor and the sensor doesn't care what clocked position its in 360°.It's not that complicated, and seals etc perfectly fine.

So check your part, make sure it's got a date code.The correct number part, it should come in a box not a baggie and should have those stupid ribs on it.

Mahalo!

Here are BOSCH-Made In Germany-Unbranded


The 'Made In Germany' (by AB) one in middle protrudes. The metal magnetic part extends past the shaft.

 

hello all, I was having random cylinder misfire, i believe it was 3 or 4 cylinders. And throwing code for the crank pos sensor. I ordered and replaced it with a Bosch sensor, however I am still having random cylinder misfire in 5, 3, 1. Has anyone else had this issue. Again I used a Bosch crank sensor. I was going to try to do the relearn driving procedure but cant make it 2 miles without the CEL flashing again and have to shut it down. Thanks in advance

 

Hey tlhayes580,

Sounds more like the bank on passenger side is lean, etc more than a than crank position prob.
What originally was the code that you had, and did it include p0305 p0303 and p0301 misfire codes or just the cps code. Or did the misfire codes show up after replacing CPS?

Since it's a whole bank, all 3 injectors or all 3 coils are not getting a proper signal... (would Cam Sensor do that?)
There's perhaps a wire loose going to that bank.
Something's going on to get all three cylinders to misfire.
O2 sensor is bad...?
Something's messing that bank up,,, an air leak just on the on that side is letting a bunch of unchecked air...? hmmm You'll need to check fuel pressure to that sides rail, check coils are firing, ... or get another CPS and try it to make sure its good, highly doubtful its bad though to cause this.

I think it's the other way around your CPS sensor was good, but the misfires were making it so the crank position code showed up because of the way it was running and misfiring.

Check connections, etc. Start simple and cheap before throwing parts cannon at it. (ie swap left bank parts to right bank)

Someone else may chime in if they've ran into this.
Thanks
