Map sensor ? code p0110

[Benni Johansson]

Hello.

I have a code p0100 p0110 and p1651.

The vsc is lighting and the engine revs only to 3000 rpm.

The triangel is flashing.

I orderd a new MAP sensor and reset the codes but the same code appired.

The volt is 5 on the cable and i don´t know what to do.

Any one having the same codes ?

P1651 is quite common on the 430 engine. It is the VSV that controls the ACIS that fails. It is a pain to replace as you need to remove the intake manifold to get to it - make sure all the wiring and vacuum hoses are in good condition whist you have access.

Not sure why the other two codes have come on - I've seen another report of all three codes coming on at once but I believe the VSV is the main issue.

Thank you, is there a way to check that? what is the vsv? Is it a sensor or a valve?

It's an air valve.

Hello again Collin.

I took of the upper inlet mainfold I did not find the valve, is it under the lower inlet or where is it lokated?

It's on the bottom side of the lower inlet - the component diagram within the thread that I first posted shows the location (COMP.PDF).
