OTC OBD I & II Scan Tool 3211
P2176 — Historical
What does this all mean? P2176 is the code. As per the user manual, "P2" means the code is powertrain-related and is a generic OBD II code as per SAE specification. The "1" designates the vehicle specific system. "76" is the fault designation. Here's what the rest of the information means:
- P2176 Definition:
- As shown in the photo, "throttle actuator control system — idle position not learned."
- CURRENT (Highlighted in Blue):
- The trouble the code indicated is active and can't be erased. In order to remove the DTC (diagnostic trouble code), the problem must be repaired.
- HISTORY (Highlighted in Blue):
- The code is also held in the computer's historical memory.
- MIL (Highlighted in Blue):
- The code caused the MIL — or Malfunction Indicator Light in the dash — to come on.
- 1/7 (Upper Right Corner):
- Indicates this DTC is the first of seven reported.
- ECM $10 (Upper Right Corner):
- This is the location designator for the control module the code was reported from.
- "MIL" and "REQUESTED" (Below):
- Means the code requested the MIL be turned on.
- "Since last key cycle" and "FAIL" (Below):
- Related to the I/M (inspection/maintenance) Monitor, this means the circuit failed the test since the car was last turned on and off.
- "Since DTCs erased" and "PASS/FAIL" (Below):
- Also related to the I/M Monitor, I don't know what it means and I was unable to find an explanation, other than that whatever "PASS/FAIL" means, it occurred since the DTCs were last erased.
- Code Criteria (Bottom Left Corner):
- Now that little "i" with the blue circle around it in the bottom left corner is a useful tool. You press the corresponding button below it on the tool's keypad to get the Code Criteria, or the detailed conditions that caused the code to be thrown.
