P202D - REDUCTANT LEAKAGE
| Description: The PCM monitors the reductant pump motor when the selective catalytic reduction (SCR) system is active but the reductant injector is closed. If the PCM must output a duty cycle greater than 50% to the reductant pump motor to maintain system pressure, a leak is suspect and this DTC sets. | |||
