December 15, 20232 yr The check engine light has been coming on and off, so we got an ECU reading at a mechanics. Apparently it is the knock sensor, from their message. Any comments, recommendations etc welcome.
December 15, 20232 yr Author They said they need to investigate why the knock sensor is bad, and it would take 1-2 days to do this. They look cheap online, less than 1000THB.

December 15, 20232 yr Author I guess it isn't an emergency fix or die situation, like faulty brakes, and a faulty knock sensor will be okay to drive for a while as we research it.
December 16, 20232 yr Cheap job even with genuine parts. Don't buy online almost certain to be cheaper fakes especially in the Land of Scams.

December 17, 20232 yr I assume this is a Mazda 2 or 3. They go bad frequently and we replace a lot in the UK. Resistance of the sensor should be 550kohm +/- 30k. If its high (usually they go over 1Mohm) replace with a genuine Mazda part. The sensor is under the inlet manifold IIRC, so need to remove inlet to replace.
