BME010202100W01

DTC P2195 DTC P2197 | HO2S (RF) signal stuck lean HO2S (LF) signal stuck lean
--- | ---
DETECTION CONDITION | • The PCM monitors the HO2S (RF, LF) output voltage when the following conditions are met. If output voltage is less than 0.45 V for 25.6 s, the PCM determines that the HO2S (RF, LF) signal remains lean. MONITORING CONDITION

  - Fuel injection control system status: feedback zone
  - ECT: more than 70 °C {158 °F}
  - Engine speed: more than 1,500 rpm

Diagnostic support note
• This is an intermittent monitor. (HO2S)
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • HO2S (RF, LF) malfunction • Fuel injector malfunction • Insufficient fuel line pressure • Leakage exhaust gas • Air suction at intake-air system malfunction
• Leakage fuel
• MAF sensor malfunction
• ECT sensor malfunction
• PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED • Have FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS (HO2S related) been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information and/or on-line repair information availability. • Is any related repair information available? | Yes | Perform the repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY RELATED PENDING CODE OR STORED DTC • Turn the ignition switch off, then ON (Engine off). • Verify the related PENDING CODE or stored DTCs. • Is the DTC P2177 or P2187 (with DTC P2195) or P2179 or 2189 (with DTC P2197) also present? | Yes | Go to applicable DTC inspection.

No | Go to the next step.
4 | IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is DTC P2195 or P2197 on FREEZE FRAME DATA? | Yes | Go to the next step.
No | Go to the FREEZE FRAME DATA DTC inspection. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
5 | VERIFY CURRENT INPUT SIGNAL STATUS • Connect the WDS or equivalent to the DLC-2. • Verify the following PIDs. (See PCM INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)

  - ECT
  - MAF
  - TP
  - VSS

• Are the PIDs normal?
Yes
Go to the next step.
No | Inspect the malfunctioning part according to the inspection results. Then go to Step 13.
6 | VERIFY CURRENT INPUT SIGNAL STATUS UNDER FREEZE FRAME DATA CONDITION • Connect the WDS or equivalent to the DLC-2. • Verify the following PIDs under the FREEZE FRAME DATA condition. (See PCM INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)

  - APP1
  - APP2
  - ECT
  - MAF
  - TP_REL
  - VSS

• Are the PIDs normal?
Yes
Go to the next step.
No | Inspect the malfunctioning part according to the inspection results. Then go to Step 13.
7 | INSPECT INTAKE-AIR SYSTEM FOR EXCESSIVE AIR SUCTION • Visually inspect for looseness, cracks or damage to the hoses in intake-air system. • Is there any malfunction? | Yes | Repair or replace the malfunctioning part, then go to Step 13.
No | Go to the next step.
8 | VERIFY CURRENT INPUT SIGNAL STATUS OF MAF SENSOR • Connect the WDS or equivalent to the DLC-2. • Start the engine. • Access the MAF PID. • Verify that the MAF PID changes quickly according to engine speed.
• Is the PID normal?
Yes
Go to the next step.
No | Replace the MAF/IAT sensor, then go to Step 13.
9 | INSPECT HO2S (RF, LF) • Inspect the HO2S (RF) (with DTC P2195) or the HO2S (LF) (with DTC P2197). (See HEATED OXYGEN SENSOR (HO2S) INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
• Is there any malfunction?
Yes
Replace the malfunctioning HO2S, then go to Step 13.
No | Go to the next step.
10 | INSPECT FUEL INJECTOR • Inspect the fuel injector for the right bank (with DTC P2195) or the left bank (with DTC P2197). (See FUEL INJECTOR INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
• Is there any malfunction?
Yes
Replace the suspected fuel injector, then go to Step 13.
(See FUEL INJECTOR REMOVAL/INSTALLATION [AJ].)
No | Go to the next step.
11 | INSPECT FUEL LINE PRESSURE • Perform the "FUEL LINE PRESSURE INSPECTION". (See FUEL LINE PRESSURE INSPECTION [AJ].) • Is there any malfunction? | Yes | Go to the next step.
No | Go to Step 13.
12 | INSPECT FUEL SYSTEM FOR FUEL LEAKAGE • Visually inspect for fuel leakage in the fuel system. • Is there fuel leakage? | Yes | Repair or replace the malfunctioning part, then go to the next step.
No | Replace the fuel pump unit, then go to the next step. (See FUEL PUMP UNIT REMOVAL/INSTALLATION [AJ].)
13 | VERIFY TROUBLESHOOTING OF DTC P2195 AND P2197 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Run Drive Mode 1 and 3 (See OBD DRIVE MODE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)

Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [AJ].)
No | Go to the next step.
14 | VERIFY AFTER REPAIR PROCEDURE • Perform "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [AJ].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection.
