As long as I have been a lurker in the forums, learning as I go, now I need to solicit some direct advice. I have a 2003 V70 with the 2.4T. I bought the car with about 148k on it and it has about 171k now. Besides the thing nickle and diming me on bulbs and spring seats, I have had pretty good luck with it in the two years I've owned it.
Months ago, it started to occasionally be hard starting, usually when hot. Sometimes the tach would jump wildly while cranking. I lived with it until last week when it got more regular and worse. I figured it was probably related to the crank position sensor, so I went to remove it. When I started to undo the nut, the bracket disintegrated (it might have actually been broken already). I ordered a new Volvo bracket (30637803) and installed it.
I installed the old crank position sensor and and tried to start the car. It started right up, but ran rough as hell. I shut it down and double checked all my connections. I also charged up the battery fully just in case that was related. The P0337 code was set. So, I ordered a new crank position sensor, a Beck Arnley 180-0492, and installed it.
With the new sensor in place and codes cleared, the car again started right up. This time it did not immediately run rough or set a code. I pulled out of the driveway for a test drive, but when I got above 1500 rpm the lights went off again for reduced engine performance, P0337. I drove around for a while and the car ran reasonably well with the trouble light resetting itself if I idled around long enough. But, if I got on it again at all it would set off the triangle.
I have checked over about everything I can think of and it will keep setting the code. I even tried the sensor off my my wife's 2005 XC90, but it behaved the same as the 'old' sensor from the V70. It seems odd to me that the old OEM Denso sensors both make it run really badly, but the new Beck Arnley only exhibits part of the problem.
I have noticed that in park or neutral, as I press the accelerator up the tach rises smoothly until about 1500 rpm. Above that, it kind of jerks/bounces up irregularly.
I would appreciate any and all advice or ideas. I spent a good amount of time with the parts and service departments at my 'local' Volvo dealer (3 hours away), to no avail. This is the fifth Volvo I've had, but this problem is new to me!

That's an interesting thought. But wouldn't one of the two OEM ones work still? Thanks for the input.

That's a good point, but it's the same identical sensor as the OEM Volvo one from the V70. So, shouldn't ONE of them work? Legit idea though. That's why I'm here because there could be something obvious I'm missing.

I DID figure it out. The mounting bracket for the sensor was not seating correctly. I had trouble getting it cinched down because of the difficult location and in doing so got it maybe a 1/16" off kilter. Once I cleared room to get a better look and took my time getting it tightened down perfectly, the problem went away.

Great! I hope that turns out to be a fix for you!
