SW1 L4-1.9L SOHC VIN 8 (1996)
CLOSED POSITION ERROR
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 commands the EGR valve closed, a closed valve position value is learned. If the PCM commands the valve closed and the actual feedback value
does not match the learned value, DTC P01404 will set.
