OBD Code P2193 - System Too Lean At Higher Load Bank 2
The trouble code P2193 can be described as System
Too Lean At Higher Load Bank 2. The error code P2193 would start triggering
when the ECM would detect that the fuel control has reached its rich limits
when the engine is under a heavy load on bank 2. One thing which you must keep
in mind is that its symptoms as well as causes would surely vary as it depends
upon a number of things.

Don’t worry if P2193 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. It is a generic powertrain as well as engine diagnostic trouble code which generally applies to fuel injected engines from most European and Asian manufacturers since 2010. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.
What causes this problem with the System Too Lean At Higher Load Bank 2?
- Quirks in the air/fuel ratio sensor/oxygen sensor (AFR/O2)
- Malfunctioning mass air flow sensor (MAF)
- Unusable powertrain control module (PCM)
Replace/Repair These Parts To Fix Code P2193
- Engine Wiring
Harness - The broken wires in the wiring harness might lead to some
serious engine problems. So make sure that you replace your faulty engine
wiring harness to avoid such situation.
- Engine Control
Module - Is your car engine light still staying ON after resetting
or your car engine is turning off for no reason? Then these are some common
symptoms indicating that your car engine control module is defective.
- Powertrain Control
Module - The PCM works as the central computer system in an
automobile’s mechanism. This auto part is the in charge of all the constituents
as well as the functions performed by them. Having such enormous importance in
the operation of all the parts means that any defect in it will affect almost
every aspect of a car.
- Fluid Pump Control
Module - If the control module is faulty, the pump will not be
able to work properly and will not be able to transfer fluid to the
transmission and hydraulic system efficiently. Thus, replacements are in order.
- Electronic Control
Unit - The ECU is a major component of your car's onboard
computer. It's used to regulate many systems and subsystems in your car's
engine, drive train and other major components. Visit us to buy best quality
ECU online.

How To Correct P2193 System Too Lean At Higher Load Bank 2
If you wish to correct this fault code, then
you have to follow certain steps. Correcting a problem needs your careful
attention. Here are some ways with the help of which you will be able to
correct the OBD Code P2193:
- It is essential to restore the flawed
powertrain control module
- Repair or replace one or more of the injectors
for bank two.
- Rehabilitate the defaults all the injectors for
both banks of the engine
- Carefully adjust the faults in the O2 sensor
for bank two.
- Make sure to carefully check the system to make
sure it does not run lean under a load
- It is necessary to perform proper service of
the unsound MAF

Easy Diagnosis Of Engine Error OBD Code P2193
Here are some steps which you should follow in order to diagnose this fault code:
- Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
- The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
- The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
- The codes should be scanned and document the codes in the engine control module and look at the freeze frame data for some defects.
- Examine the O2 sensors for bank 2 while manually enriching the mixture with propane to see if the O2 sensor indicates rich.
- Remove all spark plugs on bank 2 of the engine and inspect to see if any plug is running lean, indicating an issue in the cylinder.
- The manufacturer pinpoint tests should be followed for the diagnosis and replacement of the clogged or faulty injector for the lean running cylinder.
Common Mistakes When Diagnosing The P2193 Code
- It is very important to clear the memory of the ECM codes before you start examining the freeze frame data for the main issue, so the failure might be identical and restored.
- Most of the times mechanics fail to clear the codes of the engine control module once the codes are fixed.
- Many a times the mechanics might fail to clean the injectors, while might have actually fixed the issue.
