P2238 FORD code

Code P2238 is a code indicating the O2 sensor heater circuit is shorted causing the circuit voltage control to be low. This will cause the fuel feedback control to not work and the ECM to put the engine into failure mode or open loop fuel control.

What is engine code P2238?

P2238 is a generic code for the engine control module (ECM) in any vehicle manufactured from 1996 onward, and it’s triggered when there’s a short circuit in the heater control circuit of the O2 sensor. The ECM is the brain behind your engine. It manages the air-fuel ratio that keeps your car running safely.

What causes P015B?

P015B code means that your vehicle’s powertrain control module (PCM) has detected a delayed response time from the upstream oxygen sensor on Bank 1. Usually, a slight decrease in fuel economy will be the result, along with an MIL light.

What causes P0052?

OBD II code P0052 is most commonly set when the PCM (Powertrain Control Module) detects a signal voltage or a resistance level from the oxygen sensor control circuit that does not fall within predefined parameters.

What causes P013A?

The PCM uses the data from the upstream oxygen sensor when calculating how much fuel to give the engine. Once the PCM detects a slow response time from the oxygen sensor (Bank 1 Sensor 2) over a set period, it will trigger code P013A.

How do I fix code P2238?

What repairs can fix the P2238 code?

  1. Replace the O2 sensor for an short circuit in the heater circuit.
  2. Repair the wiring connector or wiring to the O2 sensor for shorts.
  3. Replace the power relay for the heater circuit due to a burned out or shorted circuit that the pinpoint test indicated.

What is an air-fuel ratio sensor?

The air-fuel ratio sensor monitors the oxygen content in the exhaust stream and sends data to the computer so that it can add or subtract fuel. If there is any problem with the sensor, it can send a bad or false signal to the computer which can throw off its calculations and cause it to waste fuel excessively.

How do I fix p015b code?

Zitat von Youtube: In order to prevent leaking get some gasoline put it in a cup and then dip the new fuel injector into it. So the seals may get wet with gasoline.

How do you clean O2 sensors?

Zitat von Youtube: Take it out you know spray. It let it soak. Again you know rinse and repeat a couple of times try to get as much of the gunk out as possible. However you're very unlikely to be able to get.

How do I fix my P219A code?

How To Correct P219A Bank 1 Air/Fuel Ratio Imbalance

  1. You must fix the leakage in the engine vacuum.
  2. Make sure to mend the faulty oxygen sensor/s.
  3. Repair or replace the quirky wiring and/or connectors.
  4. Rehabilitate the leakages in the engine exhaust.

What is a P0052 mean?

Cost of diagnosing the P0052 code

P0052 is a diagnostic trouble code (DTC) for “HO2S Heater Control Circuit High (Bank 2 Sensor 1)“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Which side is Bank 2 sensor1?

Bank 2 Sensor 1 (a.k.a. B2S1) is located on the side of the engine with cylinder 2 in the firing order and the O2 sensor situated in front of the catalytic converter. Depending on the car’s make and driver orientation, it could be found on either the driver or passenger side of a vehicle.
