New to the D12 engine

I think it sounds more like a throttle position sensor

 

Where is the throttle position sensor
If its the accelerator assembly I replace that already
2 bolt took the pedal and the sensor
If that's not the throttle sensor where is it located
Any help would be very much appreciated
I cannot afford to take it to the dealership
I have another engine I can take parts off of to get it going
Thank you folks

 

I had a Friend tell me it's the egr valve
I'm not sure if it has a egr valve the engine enables is a d12 in a 2000
But it it was a egr valve that would not explained the engine going g back to normal after you let the accelerator all the way up and repress it or the blinking Hud screen like someone else Takei the batteries loose and hooking it back up quick
It has me stumped

 

is it throwing ANY codes?

 

Yeah but the dealership is 100 miles away and want 250 just to hook it up and 150 a hour

 

I don't know about the older volvo's but my 2005 can read the codes right from the dash

 

It has some code
I called that dealship and told them the codes I got they refuse to talk to me and told me to bring it to them
I notice a few of my relay are bad hot after driving 10 mile so I replaced them
I still have one new one getting hot it's the ph1 acc
I'm not sure what that does
I'm thinking they are getting too hot and over loading I my put a heat sink on it to help keep it cool

 

I have not found a place to find out what those codes are
Are those relay suppose to get hot

 

The relays will normally get fairly warm, what are the codes you are getting I might be able to help
