P1332 (Knock Sensor) and P0014 (Cam Timing) – Could This Be ETM Related? [1999 Volvo S70 GLT]

[jmartin919]

Why did you replace the front mount? Was it leaking? Engine vibration? Were all mounts replaced? Did you notice a difference with the new mount?

[ericmci]

The rear had split and lost all it's fluid.
But the rubber alone was keeping it fairly steady.
And the side pad kind of needed it. But I think they were all original and honestly it's not a huge difference
But one of those repairs I wanted to do all at once to equalize the repair effect you know?
So I did them all at once.
I would say the trans torque mount made the biggest difference- also the easiest one to do.
I *Can see a difference after it is more steady at idle and load.
It was worth it.
But more of a nice thing to have than an essential for my car.
Much like the subframe bushings I have in my garage waiting to go in.

I just realized that I could check the part number with my boroscope
and it is in fact the Camshaft Position Sensor.
For my car it is 9186811

I love this little bit--
This year has some really weird 'quirks' when it comes to parts and manuals:

Camshaft Position Sensor – Volvo S70 GLT (9186811)
Volvo Part Number: 9186811

Application: Camshaft Position Sensor

Mounting Location: Despite being listed in some places as for the "exhaust cam", in your Volvo S70 GLT (especially 1999–2000 models with CVVT on the intake cam only), this sensor is physically mounted on the end of the intake camshaft.

Why Does It Say "Exhaust Cam" Then?
This is where the confusion often comes in:

Parts catalogs and aftermarket sellers sometimes refer to it as an “exhaust cam” sensor because in other later Volvo engines (with dual CVVT), there are sensors on both cams, and the naming convention stuck.

On your 1999–2000 S70 GLT, CVVT is only on the intake camshaft, and there's only one camshaft position sensor — and it monitors the intake camshaft.

The sensor is installed at the rear of the cylinder head, which is the transmission side — this is often mistaken for the exhaust side due to the turbo being nearby, but it’s still mounted on the intake cam.

Would you say the trans torque mount took out a lot of the vibration at idle in Park and Drive? Do you know which brand you used? I bought a Febi-Bilstein and it was so flimsy I sent it back and put the original back on.

[ericmci]

It can affect it- it definitely made a difference in shifting through park- Drive.
I would also point to the front mount.
I didn't know mine was split until I removed it. The weight of the engine keeps it feeling pretty firm
and any sign of a leak was long gone.
I got my mounts from FCP but this one seems to be out of stock by:
Hutchinson - Lower Transmission Torque Mount

Just always stay clear of URO

[jmartin919]

For those interested. A disected OEM rear engine mount from a 2000 S70 GLT SE that was leaking.

. I saw in another thread that aftermarket mounts maybe solid rubber and not hydraulic. I did replace my rear mount with a Corteco so maybe that's why I have the vibration?

[ericmci]

Well it doesn't appear that my P0014 was coming from a dirty sensor.
Good news - my seal is intact.
But the next trigger for this code would seem to be try cleaning the cvvt.
And doing a final confirmation of the timing marks.
I suppose the Camshaft Position sensor could be faulty itself - but would that present itself all the time?

Here is the shiny sensor.
There is some very light scoring on the bottom but it was pristine clean.
