Hi every one
Im new on the forum, done some reading and found interesting topics.

Hope you can help me.

I have a 2005 Vito 115 W639 engine code 646

It goes into limp mode if rpm goes over 2000

I get the following errors from my ELM327 WIFI module connected to my iPhone:

P2018 Intake Manifold Runner Position Sensor/Switch Circuit Intermittent (Bank 1) Status of this DTC Test failed since last clear Test not completed this operation cycle Warning Indicator requested Engine state when the fault appeared No data available Report generated with EOBD-Facile App compatible with iPhone/iPad

P2016 Intake Manifold Runner Position Sensor/Switch Circuit Low (Bank 1) Status of this DTC Test failed since last clear Test not completed this operation cycle Warning Indicator requested Engine state when the fault appeared No data available Report generated with EOBD-Facile App compatible with iPhone/iPad


I have already stripped the inlet manifold in search of the intake "flaps" but found a old-school manifold is still used on my model, no actuator, no flaps in the manifold.
Im now cleaning and busy putting everything back.

Any advice on where to look?

Thanks in advance
