Suzuki Swift 4 cyl ?

The engine crankshaft wheel was modified, and the ECU was also modified (apparently originally ordered with VR, HALL, but changed to HALL, HALL ?).

Maybe the pullup resistor was installed on the wrong side ? (not the input, but the internal side of the protection resistor ?)

ECU primary trigger HALL input passed test of 720000 pulses / minute (12000 RPM with 60-2 config, equivalent 20000 RPM with 36-1 config) without any sign of problem.

Bad sensor test was not done. Eg. 1 diode can simulate a sensor that cannot pull down to below 0.4V (as a good HALL sensor), but only to appr 1V. That would be interesting...


Do you have oscilloscope ?

cranksensor: factory 36-2-2-2 HALL was replaced with

36-1 HALL.

v3 ECU has HALL, HALL input


When engine is warm, trigger error (and misfire) above 5500 RPM.

It is suspected that primtrig HALL sensor does not pull to GND (or to <0.5V) as it should but perhaps to 1V or so ?

  • they claim the sensor was replaced (with another factory HALL sensor of same type) and problem persists, so it is reproducible
