Hi Balaji Subbiah,

You sure you got the code or description correct?

Data I found for the code indicates a faulty HOS sensor located on the exhaust before the catalytic converter.

Hello Balaji Subbiah,

Mitsubishi's manufacture specific code does say that code P1400 is "Manifold Differential Pressure Sensor Circuit Malfunction".

However, I agree with KHLow2008 with the O2 sensor.
