P2180 code definition

The P2180 code indicates that the PCM is unable to control the fuel/air mixture for engine bank 2 off idle.

What the P2180 code means

In order to maintain the proper fuel/air ratio, the PCM controls how much fuel is supplied to the engine. If the PCM detects, via data from oxygen sensors, manifold air sensors, mass flow air sensors, and throttle position sensors, that the fuel conditions in engine bank 2 are too lean, it will assume a fault and store the P2180 code.

What causes the P2180 code?

There are many causes that could create the conditions in which the P2180 code would be stored. Those may include:

What are the symptoms of the P2180 code?

In addition to the illuminated Check Engine Light, drivers may observe a lack of power during acceleration, misfiring engine during start up, stalling engine during start up, black smoke coming from the exhaust during start up, or hesitation during start up. Some vehicle may exhibit no symptoms at all, however.

How does a mechanic diagnose the P2180 code?

In order to properly diagnose this code, a technician will need an OBD-II scanner, as well as a digital volt/ohmmeter and an infrared thermometer. After verifying the code with an OBD-II scanner, the first step is to visually inspect all electrical components, and to replace or repair any that are loose, corroded, short, or damaged in some way. Always be sure to clear the code and retest the system after each repair, to ensure that the proper diagnosis was discovered.

After this process, if the code returns to the PCM, the next step is to test the engine and the fuel system for proper operation. Using the digital volt/ohmmeter and the infrared thermometer, the mechanic should test all parts and compare the readings against the manufacturer’s specifications. Once the fault has been found and replaced, the code should be cleared and the system should be tested once more.

Common mistakes when diagnosing the P2180 code

This code is frequently accompanied by camshaft or crankshaft sensor codes, low fuel pressure codes, and ignition misfire codes. In the event that any of these codes are present with the P2180 code, the most common mistake made is to not diagnose and repair the other codes first. The P2180 code can be stored due to a communication failure caused by one of these codes.

How serious is the P2180 code?

The P2180 code is a very serious trouble code that should be dealt with as soon as possible. Even without symptoms present, ignoring this code can lead to engine damage, or damage to the catalytic converter.

What repairs can fix the P2180 code?

There are many ways that a technician can address a P2180 code detection. They include:
