That is the error coming up/\. Any help appreciated.

Comes up in what - a generic scanner, or an Mbstar / das system?

and on what, a gas or a diesel?

Icarsoft 980 scanner, GL450 gas engine
It may have said changeover not crossover. Also said catalytic converters were inefficient. I assumed that is because the air flow is wrong so running lean or rich.

I cleared the codes. I'll let it run a while and scan it again today

Thanks for responding

Could be your intake manifold flap actuator arm has broken off and intake manifold position isn't corresponding with the commanded setting...
That is a common M273 problem.

If a visual inspection reveals a broken actuator pivot, just rotate the central pivot all the way clockwise, ensure that the vacuum clock actuator arm can't touch it any more (but don't restrict it's in and out movement) and forget it ever happened. Rotating the central pivot to clockwise avoids a CEL. These flaps do little if nothing for fuel economy or performance.

I'm sorry I'm all over the place on this.
Codes are P0410 Manifold secondary air pump.
When I look at "Actual data" it indicates the "intake manifold changeover - short."

Problem 1. P2004 code from the intake baffles. Well the center arm is indeed broken. I positioned it as described above.

Problem 2. I tested the air injection pump by jumping of the battery jumper terminals, all I got was a spark. I replaced the pump. I fear the fuse/relay is blown, researching its location now.

Problem 3. Code P0015 and P0012 showed up. Do I need new sensors?

Thanks





Thanks

Replaced secondary air pump and fuse, rotated the central pivot all the way to the clockwise position. Drove about 50 miles, no DTCs Yippee.

Now the microphone, it doesn't seem to pick up any sound.
