Knock sensor values

[johnpatsa]

After changing coils plugs and tps my bile starts running like normal...just a last issue..why the Knock sensor saws different values cylinder 1&2?maybe synchronization? also nthe lambda 1&2 has a little different values

It is important that knock sensors are fitted correctly. The securing bolt has to be tightened to the correct torque. Overtightening a knock sensor bolt will scrap the sensor.

I think they are a piezoelectric sensor and very sensitive.

So, was it the secondary coils causing the rough running?

I think all the 4 of them...at 85000km...after change much smoother running

Thanks John, I think mine maybe the same, 153,000 miles and what looks like the originals......

Did my secondaries not so long ago (Beru), gonna order a pair of primaries soon. My secondaries improved running so hopefully new primaries will also help, mine sometimes has a wee stumble and a spate of rough running.

Sensor values on my 2010 GSA today.

Can you post running values on idle...to see the differences

......and preferrably at normal running temperature.

Ok, tomorrow.��

Also give as the spark advance angle...mine is 12º

Thanks a lot my friend...so i think a kind of difference between Knock sensors may be normal..
