SPIKE":8hfjs61s said:Not that it helps but, the gap to the reluctor ring should be about 15 to 20 thou or max of 0.5mm (20thou) i have had problems with non specific sensors not working then a genuine Bosch or Marreli works.
IMHO i think you will work it through but i feel that scanning for fault codes is a waste of time, it tells you what happened and not whats happening. get a good scanner that can display four or more inputs and watch the screen, if the ECU is getting the signal it WILL be displayed and therefore work and visa versa. Battery voltage is critical and constant cranking can push the volts too low, run a big slave battery whilst testing or a dedicated charger with about 70a capacity to keep the volts up.
Good hunting.
Thanks for confirmation on gap. We were using < 1mm ~ 0.4mm. The replacement purchased was a Facet version. Even if it is a bad sensor/gap, is it normal for the ECU to stop reading the data? In other words, shouldn't the ECU keep reading data, albeit in error? Situation now seems like the ECU is commanding relays to shut down the whole ignition/injection system.
Both TDC/CPS sensor units gave exactly the same readings. Data stream showing about 150RPM before dropping to zero even though starter was still turning at full speed. Manual states 250RPM should be expected. The data cuts out at precisely same time as voltage cuts out as measured at ECU and Relays.
Have tried every method, trickle charging the old batt, large amp slave batt, as well as a new batt. Wished it was an amp issue.
