P2062

DTC P2062, sometimes indicated as P206200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing reductant/regeneration supply control circuit/open.

The DTC code P2062 is defined as "Reductant/Regeneration Supply Control Circuit/Open". This code is set when the PCM (Powertrain Control Module) detects a malfunction within the reductant/regeneration supply control circuit.
Possible causes of this code include a defective reductant/regeneration supply control module, a wiring issue, a failed sensor, or a defective fuel pump.
The best way to diagnose this code is to use a scan tool to check for fault codes related to the reductant/regeneration supply control circuit. If any fault codes are found, the root cause of the problem should be investigated and fixed. If no fault codes are found, the wiring and connectors in the system should be checked for damage or corrosion. If no damage is found, the sensor or fuel pump may need to be replaced.
