Post subject:  Baleno CKP sensor air gap
Does anyone know the specified air gap for the CKP sensor (crankshaft position sensor)?
The FSM just specifies gap "B"

I had a few issues with getting my current baleno conv running; it just wouldn't seem to fire, occasionally ran but ran like a sack of shit,
and times seemed like it was retarded or the firing at the wrong time.

I checked all the timing pulleys, marks, piston strokes, valve movement multiple times (had the timing cover off to fully check it).

After checking the wiring and removing lots of possible issues, and probing and testing, and testing various spares, I determined the problem to be the air gap between the CKP and wheel was insufficient.

I filed the CKP sensor to allow it to be closer, and it runs fine now.

I'd love to know what it's supposed to be, especially if i need to remove more, or if I have removed too much.

I've got a Baleno motor that I haven't pulled the sump or sensor off yet I could measure what the depth is from the timing ring to the flange of the sump if that helps.

Just shave a mm or so off the sensor, i had to do it with mine even though sump was dead on level with the baleno segment.
If you shave too much and it does contact just ad a shim or some gasket paper

That'd be great.

That's what i've done, but I'd like to have some "science" to it which is something that we can search/refer to later.

Just put some playdoh or bluetac on the end of the sensor and put it in, it wont stick to the crank and will give u your clearance measurement

I got 1.1mm as the gap. Height of the sensor was 11.85mm. Depth between the OD of the timing ring and the bottom side of the sump flange was 12.95mm. Measured with the depth gauge on digital verniers

Thanks

Which tooth was it?
The single pointy type one or just one of the regular teeth.

I'll measure mine now its running tomorrow before I put the timing cover back on.

One of the smaller individual teeth just like the diagram above

After filing down an amount I didn't measure, it is running fine, the gap is now 0.94mm.

The sensor was sitting flat/parallel to the oil pump housing (unlike the CairnsZook baleno install thread), I measured with feeler gauges as the timing cover was off.

I forgot to measure yesterday, but I'll measure what it was prior to filing.
