Code P1406 Saturn Description
The P1406 diagnostic trouble code for Saturn vehicles relates to the EGR (Exhaust Gas Recirculation) valve pintle position circuit. The EGR system is an important component in the vehicle's emissions control system, as it helps reduce nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust gases back into the intake manifold. The EGR valve controls the amount of exhaust gas flow into the intake manifold, and the pintle position sensor monitors the position of the valve.
