Nissan N16 Pulsar and A33 Maxima ECU Idle Control Problems
Low idle, stalling, erratic idle, high idle
A common fault with the N16 is with the idle speed stepper motor assembly. The coolant leaks through the
aluminium housing causing the electrics in the idle motor to fail.
In the majority of cases not only is the idle motor
assembly damaged but causes the ECU idle driver circuit to fail.
If the idle motor tests faulty then the motor will need to be replaced.
As it is very common for a faulty idle
motor to cause damage to the ECU then it is highly recommended to have the ECU tested.
CoolDrive EFI Division can test the idle motor
and the ECU.
CoolDrive EFI Division also provide repair/parts packages for the ECU/motor some of these are detailed
below or contact us for more information.
