Caution / Notice / Hint

HINT: 

Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1. PID Item/Simulation Item Used In Diagnosis (200 Pin Type) 
   PID/DATA MONITOR ITEM TABLE
   
   

   Item	Definition	Unit	Condition/Specification
   Heated Exhaust Gas Oxygen Sensor (bank 1, sensor 1)	A/F sensor current	μA	Idle (after warm up): 0-50 μA Deceleration fuel cut (accelerator pedal released from engine speed of 4000 rpm or more): Approx. 3.84 mA

2. PID Item/Simulation Item Used In Diagnosis (186 Pin Type) 
   PID/DATA MONITOR ITEM TABLE
   
   

   Item	Definition	Unit	Condition/Specification
   Heated Exhaust Gas Oxygen Sensor (bank 1, sensor 1)	A/F sensor current	μA	Idle (after warm up): 0-50 μA Deceleration fuel cut (accelerator pedal released from engine speed of 4000 rpm or more): Approx. 3.84 mA

3. Intention of troubleshooting procedure (200 Pin Type) 
   • Step 2-4
     • Perform an inspection of the A/F sensor and ECM-related connectors and wiring harnesses.
   • Step 5
     • Perform a unit inspection of the A/F sensor.
   • Step 6-7
     • Verify that the primary malfunction is resolved and there are no other malfunctions.
4. Intention of troubleshooting procedure (186 Pin Type) 
   • Step 13-15
     • Perform an inspection of the A/F sensor and ECM-related connectors and wiring harnesses.
   • Step 16
     • Perform a unit inspection of the A/F sensor.
   • Step 17-18
     • Verify that the primary malfunction is resolved and there are no other malfunctions.
