Guide To P2239 OBD Error Code Solutions
OBD Code P2239 - O2 Sensor Positive Current Control Circuit High Bank 1 Sensor 1
Your vehicle will have an oxygen sensor which has the job to
measure the amount of oxygen present in the exhaust gasses released after the
combustion process has happened. The P2239 code is set when there’s a fault
with the sensor. Your car's Powertrain Control Module (PCM) will set the code
and the check engine light will be turned on to let you know about it. This is
a generic OBD-II code and so don’t worry about it and read on to know more
about the issue and how to diagnose it.
Learn More About OBD Error Code P2239
The P2239 code is defined as a O2 Sensor Positive Current
Control Circuit High. The code is indicative of a voltage from 02 sensor
positive current control circuit is more than the range specified by your vehicle’s
manufacturer. This problem is detected by the PCM and the code gets set.
What
causes this problem with the O2 Sensor Positive Current Control Circuit High
Bank 1 Sensor 1?
- There are defects in the oxygen sensor/s present
- There are burnt, chafed or broken wires and connectors
present
- PCM is not functional or has some programming error
Replace/Repair These Parts To Fix Code P2239
- Powertrain Control Module - The PCM is main processing unit of your car and managed all the other modules of your car. It sets the error codes when it detects an issue that needs attention. Repair or replace as needed, to find the perfect replacement visit PartsAvatar.ca.
- Oxygen Sensor - Is a crucial part of the exhaust system and is responsible for recording the amount of oxygen present in the exhaust gasses emitted after combustion. Find the replacement for your vehicles’ oxygen sensor on PartsAvatar and avail free shipping on orders above CAD $99.
- Digital Volt Ohm Meter - Is a multipurpose instrument which combines different measurement functions into one so that you can diagnose issues in your vehicle. It is very helpful if you need to carry out diagnosis regularly, if the one you have isn’t working properly replace it.
- Exhaust System - This is a system responsible for directing the waste exhaust gases away from the combustion of the engine. Try to repair the issue that has been noticed, and see if the P2239 code still returns. If the code still persists, you will have to go for replacement. Order online from PartsAvatar and track your order till it reaches you in just few days.
- Engine Control Module - The ECM is a central part of your vehicle that has the big responsibility of managing all the other modules in the vehicle. Always ensure there are no issues with the ECM, as that can cause the P2239 code to be set. Repair or replace as needed.

Easy Diagnosis Of Engine Error OBD Code P2239
If
you want to easily diagnose this fault code, then all you have to do is to
follow the steps which are mentioned below:
Start
by firstly locating the oxygen sensor that is upstream and on bank 1 and noting
any issues with it. If you don’t know the exact location, make use of your
vehicle Technical Service Bulletins for the same. You will find plenty
diagrams, charts etc. to assist you. All the inspected problems should be
repaired, if you think repairs wouldn't hep, then go for replacement.
Inspect
the wiring and the connectors also, be very careful and thorough in doing this.
Any damaged, burned, chafed wires or broken pins will have to be replaced.
If
you didn’t find any issue with the sensor or the electrical components then
test the fuel pressure and the vacuum readings by appropriate tools. Match the
readings with the specifications prescribed by your vehicle manufacturer. If
there’s no problem there, then test the PCM. Any issues with the PCM will have
to dealt with appropriately, replacement of PCM requires reprogramming by a
professional diagnostician.
