MAP sensors

Post by richtbiscuits » 18th June 2019 - 7:22pm

I pulled three MAP sensors out of my parts store on Sunday. I always supposed there was only one type but on inspection they all have different part numbers: vw 022 906 051, 022 906 051 E and 311 906 051 C (the Bosch numbers are 0 280 100 003, 0 280 100 049 and 0 280 100 007 respectively). One is clearly a type 3 unit the other two I suppose are for type 4 engines. Could anyone tell me if these parts are all interchangeable and which vehicles they were originally from. Thanks.

After some interweb searching I found lots of info on the old timers website which gives make and models for the sensors. There's also a very useful video which shows how to test the sensor which I did. Turns out all the sensors are good. I switched one for the one on my car then tested it and found it held no vac - torn diaphragm - which might explain the 17 mpg and rich running!

Good to hear, sorry I couldn't provide an answer for you immediately.

Can you give a link to the useful website ?

Search https://oldtimer.tips (sorry, not sure how to create a link). Loads about D-jetronic and K-jetronic systems.

Seems links create themselves when you press submit. Learn something new every day, eh.

here's a link

https://oldtimer.tips/en/

You create it by clicking on the chain (second icon from the right above) and putting the address between the brackets or by putting the url with [url ] at the beginning and [/url ] at the end....... but lose the space I had to insert after the l in each bit of code to get it to display in this post

I hadn't come across this website before :thumbsup:
