Circuit High Input codes like C2181 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

C2181 Error Code Repair Process :

When you turn on the ignition, the Service Engine Soon or Check Engine C2181 light should flash briefly, indicating that the OBD system is ready to scan your vehicle for any malfunctions. After this brief flash, the light should stay off while you drive as long as no problems are detected. If egr calibration low so, you'll be glad to know that your vehicle is equipped with an early warning system that could save you time, money, and fuel in addition to helping protect the egr calibration low.

C2181 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.

Common Causes of C2181

A common cause of code C2181 is the failure of EGR Calibration Low, but there are several other possible causes as well, such as ;

Camshaft Position Sensor harness is open or shorted
Faulty oil control valve (OCV)
Erratic camshaft position due to low oil pressure
Variable Valve Timing (VVT) circuit is open or shorted
