SW1 L4-1.9L SOHC VIN 8 (1996)
The linear EGR system consists of a linear EGR valve, the PCM and its associated wiring. The EGR valve solenoid is controlled directly by the PCM
when certain conditions have been met. The PCM contains a diode feedback circuit which dissipates energy when the valve is cycled Off. When the
PCM grounds the valve, the diagnostic feedback signal can determine if the valve had actually moved. DTC P0404 has been defined to monitor the
feedback signal. This diagnostic will determine if the position feedback signal properly falls within the correct range under different valve operating
conditions.
