Code Definition

P2180 — Fuel Trim Rich During Cruise/Acceleration (Bank 2)

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Holden

About P2180

P2180 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Holden vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2180 is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P2180 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Engine Control Module (ECM) monitors short term and long term fuel trim for bank 2 during closed loop operation, particularly under steady cruise and acceleration. DTC P2180 is set when the ECM must apply excessive negative fuel trim on bank 2 to maintain the commanded air fuel ratio, which means it is pulling fuel out because the mixture is richer than expected. The fault exceeds the calibrated correction limit for a set period before the code stores. A persistent rich condition on bank 2 can foul spark plugs, raise emissions and fuel consumption, and may produce a fuel smell, black smoke...
