Title: MAP sensor
Post by: Mikecocos on May 04, 2018, 02:16:16 PM

Where is the MAP sensor on a V7 I?

Cheers,

Mike

I want to know 'Where is the info in Service Manual', not even a mention, for V7 & Cali14.

Intake pressure would be on the intake, nothing there but an injector, so I would sat it's on a hole in the throttle body.

On the 14’s it’s on the plenum chamber. I off to deliver a Sport to Orange today but prod me on Monday and I’ll try and take a few pics of bits and bobs of the Cali, (Including the alp of anti vibration crap!).

Also, unfortunately, I won’t be using the 14 gearbox in the Stelvio project because t doesn’t have a ‘Neutral’ switch like the earlier boxes. It has a gear indicator switch on the back of the box which must send multiple signals unlike the previous go/no go earth switch. Why they did this I have no idea as the earlier bikes ECU just works out what gear it’s in just fine and uses that to adjust stuff like the torque tables. You’d think that it would be simple enough to incorporate a simple bit of logic like that into the 7SM system and run the gear indicator off that rather than using a stupid, complex, switch? (And buggering up my chance to have a shock absorber in my gearbox! :violent1:)

On the V7 it's built into the throttle body/ECU.

For the Cali 7SM, it's on top of the manifold. It's a T-MAP sensor (combo temperature & manifold absolute pressure).

Hmmmm.....

Can you remove the sensor without removing the throttle body?

You can't remove the sensor. It's integrated into the ECU circuit. It's not serviceable. Failure means new ECU/Throttle Body.

Why do you want to remove it?

I wanted to clean it. I noticed some oil in the airbox, due to overfilling in my last oil change. I was going to clean the throttle body and map sensor to remove oil and gunk.

A good wipe and a squirt or two of something like Liqui Moly or CRC MAF sensor cleaner should work.

How does the excess oil even end up in the airbox? Isn�t the air flow from the airbox to the engine?

Apologies if this is a dumb question.

There is a hose hooked up to vent the crankcase pressure from block.
