Any Auto Eletricians Out There, Please ?
Car: '05 Honda CR-V Petrol.
Problem: Engine Warning Light back on after Knock Sensor replacement.
Question 1. If I remove warning light and fault code (P0325) with my basic Memo Scanner will it re-appear if the fault still exists ?
I think the sensor is a good quality aftermarket product but I suppose there is a possibility that their is a connection fault ( The wire is quite thin).
Question 2.How do I confirm which of the two is at fault without paying out another load of cash. The fitter ( a good one) says car electrics are beyond his espertise.
Cheers.

In answer to question 1, the answer is yes.
When the vehicle diagnostics throws a fault code, it is always worth cancelling the code (if the system allows) to see if the code returns.
In my experience, even once the faulty part is replace, you still need to cancel the code to switch off the warning light.
The link below gives some advice on checking the knock sensor.

If it is a genuine fault, I would expect you to detect knocking of the engine – as noted in the above link, it may be noticeable under acceleration.
In olden days (before such on board diagnostics) having the ignition timing too advanced (causing early fuel ignition) would result in engine knocking.

Many thanks to you both, especially for the link you provided , Hymie.
And Tony, oh, how I well remember those wonderful days. Head under the bonnet for hours, checking ponts gaps with a feeler gauge, cleaning or changing points. Getting the timing spot on by slackening and rotating the distributor and using a strobe light. Doing a de-coke over the weekend, including grinding the valves.
All gone, sadly.
Cheers.
