My Engine check light is on and I got the code ""P1400 Manifold Differential Pressure Sensor Circuit Malfunction (Mitsubishi) "".

Please let me know How much it will cost to fix it. And the exact part I need to change.

Additional information: It is taking more GAS now.

Please help.

Thanks

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.
