What does trouble code P1131 mean?

Error Code P1131 is displayed when sensor 1 or the oxygen sensor bank 1 does not switch enough to lean. This trouble code tells drivers that the system is fixing the overly “lean” situation with a “rich” one in the air-to-fuel ratio of the engine.

What does P1151 code mean?

What Is a Ford Trouble Code P1151? This trouble code is signaled by your heated exhaust oxygen sensor, or HO2S. This sensor is used to test the amount of oxygen to ensure an accurate air/fuel ratio. A failed test means there isn’t enough air mixing with your fuel. This could be the result of improper air intake.

How do I fix a P1151 code?

1999 Ford Explorer has a P1151 code what could it be?

  2. Check for air leaks in the EGR system and in its related hoses and/or valve.
  3. Check for air leaks in the PCV system and in its related hoses and/or valve.

What does oxygen sensor Bank 2 mean?

The O2 sensor 2 is the downstream O2 sensor and it measures the amount of oxygen in the exhaust gases leaving the catalytic converter (cat). OBD code P0158 is set when the O2 sensor 2 has been emitting a voltage signal above its normal range for a certain amount of time.

What does P0155 code mean?

Code P0155 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 2 and detects a short in the circuit or excessive resistance in the heater circuit.
