Hi guys ,

I have a 97 Omega 2.5 V6 CD .
It had the head gaskets replaced a few months ago as well as the rocker valve cover gasket.

A few weeks ago  I was getting intermittent starting problems .

Twice the AA came out , and both times it started as soon as they got there.  They couldn't find anything wrong and their Laptops couldn't access the diagnostics.

When I tried the paperclip check , I got an error 19 , was told it was crank sensor.  Which is odd because the crank sensor had been changed whilst the head gasket had been done.

Anyway brought new sensor as soon as payday hit.
Decided to remove old sensor in preparation of it arrival :-)
When I remove the old one ,  there was a clump of metal shavings on the end.  Wiped it clean and checked hole for more looked clear. On a hunch replaced it  and tried the car , started on second try.  Drove home , went to take wife to the shop and it wouldn't start again. Again paper clip test this time error 89.

Today replaced the old sensor with the new , still the same problem and same error code.

Phoned my cousin , who did all the hard work on the car for me (hi Cuz),  was told to check the coil pack to make sure I hadn't dislodged the wire when fitting new sensor , but that was fine . Still unplugged and replugged to make sure.

STILL she wont start ,  tried paperclip test again ,  now reading 2 errors,  89(again)  and 31.

What can I try next ??

Cheers

Hi,

Code 89 is   O2 Sensor 2 Open Circuit

Code 31 is   No Engine RPM Signal, this is when your testing but not got the engine running.

Wonder if iron filings on crank sensor are affecting it?

Is the replacement sensor you fitted a genuine Vauxhall item or a pattern? Some of the cheap pattern sensors have been known to be faulty from the start

That was my 1st thought, but the 2nd time I remove the sensor there was no metal filings .

Didnt buy direct from Vauxhall, but I think its labeled BOSCH , though not 100% sure.

There could lie your problem.

is there anyway to check if the sensor is faulty ?? other than putting in the car ??
