In order to achieve the require temperature, a heater element is included inside the air-fuel ratio sensor. The ECM controls the air-fuel ratio sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications." property="og:description">

Debris in the MAF sensor can also set this P2195 code.

1. Remove the MAF sensor, and check for debris (lint, bugs, foreign objects, etc.).
2. Open the air cleaner housing cover, remove the air cleaner element, and check it for damage.
A damaged air cleaner element lets debris get into the MAF sensor. Replace the air cleaner element if needed.
3. Clean out the air cleaner housing. To keep from contaminating the MAF sensor, don’t use compressed air; use a vacuum instead.
4. Reinstall the air cleaner element, the housing cover, and the MAF sensor.
5. Clear the DTC.


What does this mean?

Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Excessive Fuel Consumption

P2195 HONDA Description

Air-Fuel Ratio (A/F) sensor need to reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal. The faster the air-fuel ratio sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the air-fuel ratio sensor. The ECM controls the air-fuel ratio sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
