CAN OBD2 tell fuel level?
Can an OBD II device read the fuel level? – Quora. No, but it does report engine ignition angle in degrees before top dead center (timing delay/advance), the vacuum load, and generates an estimated fuel consumption per hour.
How to test an O2 sensor with an OBD2 scanner?
O2 sensor reveals the symptom that your vehicle is running at optimum efficiency or not. There are a variety of ways to test an O2 sensor. Using the OBD2 scanner is the easiest and most effective way to check your sensor. 1 How to Test O2 Sensor with an OBD2 Scanner? 2 What Does an O2 Sensor Do? 3.1 1. Zirconia Sensors 3.2 2. Titania Sensors
How much does it cost to read an OBD2 fault code?
If you visited a garage to read the fault codes from your vehicle, you probably paid about $10-150 just for them to read the codes from your vehicle and do some troubleshooting for you. These costs can be reduced if you get an OBD2 code scanner for home use. There are many different scanners in all price ranges on the market.
Why do I get No reading on my OBD codes?
Check your fuses to see if any have gone bad. Remember that your car or truck might have more than one fuse box. This should be covered in your owner’s manual or a proper service manual. Another reason for getting no reading is that the scan port has become clogged with dust after years of not being used.

What to do if the OBD II scanner doesn’t communicate with the vehicle?
What to do if the OBD II scanner doesn’t communicate with the vehicle. TEST 1: Connect the positive DMM lead to DLC pin 4 and the negative DMM lead to the negative battery terminal, using jumper wires if necessary. Do not connect to the body or chassis ground but to the battery terminal directly.
When to use the OBD 2 misfire monitor?
The OBD II misfire monitor is normally active when a warm engine is running under normal loads, but it may not track misfires if other fault codes are present or codes are pending for the fuel system, evaporative emission control (EVAP) system or EGR system.
What is the lean code for an OBD 2 engine?
The OBD II system may or may not detect the fault and set a lean code (P0171 and/or P0174) in addition to misfire codes. Unmetered air that gets into the engine behind an airflow sensor can lean out the fuel mixture to the point where it may not ignite when the spark plug fires.
Why is my OBD not working on my catalytic converter?
The OBD II system can’t evaluate the converter if the upstream and downstream O2 sensors are not functioning normally. So any O2 sensor problems have to be dealt with before you can use the OBD II system to diagnose the converter. O2 sensors typically fail because of old age or contamination.
