DTC Descriptor

DTC P2096

- Post Catalyst Fuel Trim System Low Limit

Circuit Description

Fuel trim bias is used by the engine control module (ECM) to keep the post catalyst HO2S voltage within a range of 580-665 mV. This allows

optimal catalyst efficiency under light load conditions, such as at idle or a steady cruise. The ECM constantly monitors how lean or rich the fuel

trim bias is commanded, to determine if the fuel trim bias is greater than a calibrated amount.

Conditions for Running the DTC

* Before the ECM can report DTC P2096, DTCs P0030, P0031, P0032, P0130, P0131, P0132, P0133, P0135, P0137, P0138, P0140, P0141,

P2232, P2235, P2270, P2271, P2272, and P2273 must run and pass.

* DTC P0100, P0101, P0102, P0103, P0111, P0112, P0113, P0116, P0117, P0118, P0119, P0420, P0443, P0458, or P0459 is not set.

* The engine speed is 1,080-3,480 RPM.

* The engine load is 17-20 % and steady.

* The Closed Loop fuel control is active for greater than 1 s.

* The front and rear HO2S are in Closed Loop.

* The calculated exhaust gas temperature is greater than 250掳C (482掳F).

* DTC P2096 runs continuously when the conditions above have been met for greater than 200 s.

Conditions for Setting the DTC

The lean correction limit for a condition causing a rich air/fuel mixture has been exceeded for a predetermined amount of time. The condition exists

for greater than 4 s or for a cumulative of 30 s.

Action Taken when the DTC Sets

DTC P2096 is a Type B DTC.
