Camshaft Position Sensor Location

[Oka]

Can someone please help me understand more of this diagram?

1. What are parts #1, #2 & #18 got to do with this diagram?
Those three parts are at the top of the engine by the oil filling spout.

2. The two Camshaft Sensor types in the diagram does not look like the one for my 2001 V70XC/XC70.
The one specified for my car has a stainless steel plug, red and white set of wires and and a wire harness.

3. Where in the world is the sensor located on the engine? All I see are for the V70. The Volvo repair manual's
location/description is vague.

Thank you.

Cam sensor is on the exhaust cam, on the opposite side of the engine from the timing belt. Bit of a PITA to get to, the upper engine mount has to come off (I think) and the air intake pipe is in the way of the retaining bolt.

Crank sensor is buried below that same air intake pipe, reads off the flywheel.

Your picture shows a normally aspirated engine, so yeah, a bit vague.

I could find this in vadis:
7/172: position sensor, camshaft, intake side
7/173: sensor cranckshaft

I have always wondered how both the turbo and the air intake hoses are attached inside at the back of the engine.
It must be a PITA to get to the connection without a multi-jointed-arm. I will give it a try to get to the air intake hose this afternoon.

Thanks you all!

Am now really frustrated. With the VIN (YV1SZ58D311023331), it shows two Camshaft Position Sensors, a $430 and a $65 which only NAPA has the first one in town. Guess my car requires the two sensors.

I made a mistake in my previous reply:
7/173 is "sensor camshaft, not cranshaft. So 7/172 and 7/173 are both camshaft sensors.

Yeah, Cam & Cran gets confusing.
Can they be tested with the Vida & the tool?

From your diagram, it looks like both are on the same side of the engine (on the driver's side).
What does those numbers (7/172 & 7/173) mean?

Why are you buying cam sensors?

In my part of the country have never seen a bad one on a 99 and up car.

And yes Vida should be able to give a live readout on them.

I know on the early cars (91-98) the cam sensor was only needed to start the car. It provided the info where #1 was supposed to fire. The crank sensor was used after that to determine spark and fuel timing.

Am planning on buying a Cam Sensor simply because I don't know what else to try to get the car started.
All the parts I have replaced so far, would start the car and after a day or two, it won't start.
I saw this page. https://www.yourmechanic.com/article...osition-sensor
All the six pointers on it, are the symptoms I have had. All points to a bad Cam Sensor problems.
I don't know what else to do.
