P0238 Chrysler Code - MAP Sensor Voltage Too High
Quick Answer
Manifold Air Pressure (MAP) sensor voltage is monitored when the engine speed is more than 416 RPM, but less than 3520 RPM and battery voltage is more than 10.4 volts. Common causes include Faulty Manifold Air Pressure (MAP) sensor, Manifold Air Pressure sensor harness is open or shorted, Manifold Air Pressure sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
