Diagnostic Aids

* A fuel system delivery condition causes this DTC to set. Thoroughly inspect all items that cause a lean condition. Refer to Fuel System

Diagnosis (LF1 China) (See: Powertrain Management/Fuel Delivery and Air Induction/Fuel Pump/Testing and Inspection/Fuel System

Diagnosis (China))Fuel System Diagnosis (LF1 Except China) (See: Powertrain Management/Fuel Delivery and Air Induction/Fuel

Pump/Testing and Inspection/Fuel System Diagnosis (Except China))Fuel System Diagnosis (LAU China) (See: Powertrain

Management/Fuel Delivery and Air Induction/Fuel Pump/Testing and Inspection/Fuel System Diagnosis (China))Fuel System Diagnosis

(LAU Except China) (See: Powertrain Management/Fuel Delivery and Air Induction/Fuel Pump/Testing and Inspection/Fuel System

Diagnosis (Except China)).

* Any un-metered air into the engine causes this DTC to set. Thoroughly inspect all areas of the engine for vacuum leaks.

* A MAF sensor condition can cause this DTC without setting a MAF DTC. If there is a MAF sensor condition, the MAF sensor parameters

will appear to be within range.

* Inspect the air filter for being the correct one for this application. Make sure that the engine oil fill cap is in place and that it is tight. Verify

that the engine oil dip stick is fully seated.

Circuit/System Verification

1. Observe the DTC information with a scan tool. DTC P2177 or P2187 should not be set.

瀚慖f there are other DTCs set besides DTC P2177 or P2187 refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic

Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) to diagnosis the applicable DTC.

2. Ignition ON, observe the BARO pressure parameter and compare the reading on the scan tool to the barometric pressure table. Refer to

Altitude Versus Barometric Pressure (See: Powertrain Management/Computers and Control Systems/Specifications/Altitude Versus

Barometric Pressure).

瀚慖f the BARO pressure is not within the range specified for your altitude, refer to DTC P2227, P2228, or P2229 (LAU) ( See: P Code

Charts/P2227).

3. Engine at normal operating temperature, observe the Average Total Fuel Trim parameter with a scan tool. The Average Total Fuel Trim

should be between -22 to +23 %.

瀚慖f not within the specified range, verify none of the following conditions exist:

* A mass air flow sensor signal that is skewed-If the Short Term Fuel Trim parameter changes greater than 20 % when the MAF sensor is

disconnected, refer to DTC P0101 (LAU) (See: P Code Charts/P0101)DTC P0101 (LF1) (See: P Code Charts/P0101).

* The air intake system after the MAF sensor for vacuum leaks

* Fuel contamination-Refer to Alcohol/Contaminants-in-Fuel Diagnosis (Special Tool) (See: Powertrain Management/Fuel Delivery and

Air Induction/Fuel/Testing and Inspection/Alcohol/Contaminants-in-Fuel Diagnosis (Special Tool))Alcohol/Contaminants-in-Fuel

Diagnosis (Without Special Tool) (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component

Tests and General Diagnostics/Alcohol/Contaminants-in-Fuel Diagnosis (Without Special Tool)) and Fuel System Cleaning (See:

Powertrain Management/Fuel Delivery and Air Induction/Service and Repair).
