Fix Or Repair Daily Mystery Cache

I know relatively nothing about cars. I don’t even change my own oil…I’m afraid I would mess something up if I did :). That being said, I’ve misplaced a part on my car and I need help finding it. It is small, black, and about the size of a film canister. I’m not sure where it is, but my car is reporting the following codes…maybe they will help.

1. Improper Ratio for 3rd Gear
2. Ignition Coil A: Primary circuit fault
3. Variable Load Control Module - Pin 1: Open
4. Air Conditioning Pressure Sensor Insufficient Pressure Change
5. System Too Lean - Bank #2
6. Exhaus Gas Recirculation Flow Faulty
7. Heated Oxygen Sensor Heater - Not on During KOER Test
8. Random Misfire Detected
9. Spark Output - circuit fault
10. Idle Air Control - Under Speed Error
11. Low Speed Fuel Pump Primary - circuit failure
12. Electronic Pressure Control Solenoid - Short circuit
13. Cylinder Head Temperature Sensor out of Self-Test Range
14. Transmission Range Sensor Circuit - High Input
15. Engine Coolant Temperature circuit - High Input

Here are the assumptions for this puzzle:

• The coordinates read from top to bottom.
• No Fishiness.
