DTC DESCRIPTION P218F (PCM) - REDUCTANT NO FLOW DETECTED
| Description: | The PCM monitors selective catalytic reduction (SCR) system performance by monitoring the rate of reductant flow and feedback from the nitrogen oxides bank 1, sensor 2 (NOx12). These values are compared to a calculated model. This DTC sets when the difference between the modeled and actual system performance exceeds a threshold and a restriction in the SCR system is suspect. | ||
