P2239 FORD code

What the P2239 code means. This trouble code indicates that the powertrain control module has detected a voltage from the O2 sensor positive current control circuit that is higher than the range of acceptance set by the vehicle manufacturer.

What causes p2a01 code?

This code indicates a problem with your exhaust system. The O2 (oxygen) sensor associated with this code measures the amount of oxygen in your exhaust. It may be that the sensor is bad, or it may mean that your exhaust has a leak. Another cause of this error may be bad connectors or wiring to the sensor.

What causes a P0144 code?

What the P0144 code means. P0144 is the OBD-II generic code which indicates that the Engine Control Module (ECM) has detected excessively high voltage from the bank 1 sensor 3 O2 sensor circuit, indicating a rich condition.

What does code poo36 mean?

P0036 means that for the engine to operate properly, the engine exhaust should have a specific air fuel ratio of 14.7 to 1 as determined by the heated oxygen sensors (HO2S), which detects the oxygen content of the exhaust.

What does code P013B mean?

Diagnostic trouble code (DTC) P013B stands for “O2 Sensor Slow Response – Lean to Rich (Bank 1, Sensor 2).” This code is logged once the powertrain control module (PCM) detects that oxygen sensor 2 in bank 1 of the engine is taking longer than expected to switch from rich (a higher output voltage) to lean (a lower …

  P0360 FORD code

How do I fix code P0137?

What repairs can fix the P0137 code?

  1. Replacing the O2 sensor for bank 1 sensor 2.
  2. Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
  3. Repairing exhaust leaks before the sensor.

What does P2A00 mean?

A P2A00 code means that the powertrain control module (PCM) has detected a voltage reading from the oxygen (O2) sensor for engine bank 1 that is outside of normal parameters.

What does a circuit high code mean?

Diagnostic trouble code (DTC) P0463 stands for “Fuel Level Sensor “A” Circuit High.” It means that there is an unusually high voltage signal coming from your vehicle’s fuel sensor. The result is that the fuel gauge will not read accurately.

How do I fix code P0155?

What repairs can fix the P0155 code?

  1. Fix broken wires or bare wires.
  2. Replace the coolant temperature sensor.
  3. Replace the oxygen sensor.
  4. Replace the power control module (PCM), in the rare case that it is necessary.

What does P144C code mean?

It appears that your emission evaporative canister purge check valve is stuck open, as indicated by the code P144C on a 2013 Ford Fusion and most other American vehicles. This can make it possible to say for sure that a damage has caused an EVAP canister purge check valve.

Where is heater control circuit bank1?

Bank 1 Sensor 1 is between the engine and the catalytic converter. Bank 2 has a sensor 1 and a sensor 2 laid out the same way. Oxygen sensors need to be heated to work. An O2 sensor won’t work below a certain temperature – for conventional oxygen sensors, that magic number is 600°F.

  P0703 FORD code

What is HO2S heater control circuit?

This code is seen when the Engine Control Module (ECM) tries to control the heater control circuit for Bank 2 Sensor 1 and finds high voltage present. The heater is an integral part of sensor function that is used to heat the oxygen sensor to operating temperature until the vehicle warms up.
