C 0 0 2 3
OBD-II Diagnostic Chassis (C) Trouble Code For Engine Intake Valve Control Solenoid Circuit Low Ambient Air Temperature Sensor Circuit Low Turbocharger Boost Sensor A Circuit Low Exhaust Gas Recirculation Sensor B Circuit High

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

C0023 OBD-II Diagnostic Chassis (C) Trouble Code Description
