Nice to hear that it is OK now. What I am wondering is that you did not see any restored codes. When my crank sensor "went" I got code 335 by using pedal trick. I guess 3.2 and 2.6 has same Motronic 3. something ECU? Did you make this pedal trick?

[Doctor Gollum]

Crank sensor rarely throws a code on the 2.6/3.2

OK, I anyway got the code, perhaps due to the fact that I had this problem a long time before I started to look it more...

Right, lets clear this up about 'money well spent'. My car was running perfectly, then one day was dead !!! No codes, nothing.!!
After reporting on here, a number of suggestions as to the cause, were received. I do not consider £10 odd spent to test the crank sensor to be 'money not well spent'. £10 is a drop in the ocean to test with, and replace with the genuine part at a later date, rather than throwing big money away on an unproven fault !!!!

[Steve B]

Sorry Terbert my mistake i didn't realise you only bought it for testing purposes...

I was referring to the idea of going out and buying a cheap crank sensor off ebay and then fitting it and owing to it working ok then thinking.."that is it i am sorted" Then a few weeks down the line your back with the same problem and yet again broken down.

It has been said on here Hundreds of times Pattern part crank sensors are junk.

[Terbs]

No problem, Steve. Thing is, many members have paid a fortune to have cars 'repaired' only to find the fault persists, and then it is repaired after advice on here for 'a pound or less'. Carrying a spare is common sense, but when you have three Omega's, a cheapy to get you home is better than a three figure sum spent on parts that might not be required.
Ironically, I have had Omega's for many years now, and, this is the first crank sensor to fail !!!
As they say, some have luck, some have babies !!!

Are aftermarket crank sensors no good on 2.6/3.2s? I have had them fail on 2.5s, but I have genuine Siemens fail on 2.5s as well. I fitted an aftermarket sensor on my 3.2 6 years ago, and it's still going strong. Just lucky?

They certainly seem far more prone to premature failure than genuine ones.  Whether or not this is because the ebay "genuine Siemens/Bosch/GM" ones are all fake (likely on ebay TBH), or some other reason.

If your pattern one has lasted well, I'd leave it in place until it fails.  But with a V6, always carry a spare if going any distance - even if you can't change it, the AA man can

Are aftermarket crank sensors no good on 2.6/3.2s? ANY ENGINE WHATSOEVER? I have had them fail on 2.5s, but I have genuine Siemens fail on 2.5s as well. I fitted an aftermarket sensor on my 3.2 6 years ago, and it's still going strong. Just lucky?

The simple answer is maybe. Crank sensors are a common failure on everything that uses them, and the advice is always the same - fit a genuine one bought directly from a main dealer. This reduces the chances of buying one cheap that doesn't last/work reliably/work at all. It's also much easier to return a non-working genuine part than it is trying to get your money back from Honest Sid's motor factors and newsagents.

I have to agree with Terbert, £10 to diagnose the fault is pretty good value. And cheap sensors tend to fail very quickly or not at all, so he might never need to touch it again.


I'm 800 miles from home without a spare, as they're not the ticking bomb we make them out to be.

my delco brand sensor still going strong after 18 months and 10K.  genuine delco - in a hologrammed box.  came with a rubber rain boot which i think is missing on the oem part, that may explain some oem failures perhaps.....

[johnnydog]

After nearly 16 years of Omega ownership, and god knows how many cars, I have only ever had two crank sensors fail - one on a 3.2 and one on a 2.2. Replaced them both with genuine items and no further problems.

[TheBoy]

My 3.0l is on its 3rd crank sensor - first failed (in France, Nick W ) at 115k, about 7yrs old, then again (NEC, when Mrs TB had used it) at about 195k/16yrs

My 3.2 is still, AFAIK, on its original.

Yes, but you get about a tenth of the reasonable life of brake pads so the part is not the problem   And I replaced mine(with a genuine part) about 4 years/20k miles ago as an attempt to fix a different problem.


I'm much more concerned about getting home with some hearing ability left due to the increasingly noisy rear wheelbearing.

Rumbling rear wheel bearings are something I dread, but you are the forum member who has changed several and has made tools for the purpose. May we look forward to to a report and guide on how you changed this one?

[Migv6 le Frog Fan]

The crank sensor I just replaced was the original and had lasted 15 years / 175k miles. It did better than most I think.
