Intake Air Temperature and Air Injection With a smartphone app like OBD Fusion or Torque, you can read tons of engine sensor data! A lower ECT means the ECU will enrichen the fuel mixture and raise the idling speed to compensate for a cold motor. The engine coolant temperature should be at 190 Fahrenheit or higher when the engine is at the ideal operating temperature. This can also mean vacuum leaks in the system.Įngine Coolant Sensor plug Engine Coolant Temperature This means the vehicle might have problems with the fuel system, injectors, oxygen sensors, or mass air flow sensor. Higher/Positive percentages in the fuel trim means the engine computer is trying to compensate for a lean condition in the motor by enriching the mixture. The ideal reading for the STFT and LTFT is within the range of 5% (you don’t want to see anything higher than 10% or lower than -10%). The fuel trim is crucial in determining how the ECU is controlling the fuel delivery in the engine.īoth the STFT and LTFT are expressed as a percentage by the scan tool. When reading live data from any OBD2 scan tool, it is best to always check the STFT (short-term fuel trim) and LTFT (long-term fuel trim). STFT (short-term fuel trim) and LTFT (long-term fuel trim). This means there is a greater quantity of live data available, which will make it easier to determine any type of fault in the vehicle, including non-engine related trouble codes including ABS, transmission, and airbag trouble codes.

Pro Tipīut in newer OBD2 vehicles that support the CAN-BUS protocol, you have up to 100 generic parameters at your disposal.

Under the original OBD2 specification (older OBD2 protocols such as SAE J1850 PWM/PWV and ISO 9141-2), up to 36 parameters are available. However, the amount of OBD2 parameters obtained will depend on the specific OBD2 protocol of the vehicle.

How to Interpret Generic Scanner DataĪll 1996 and newer vehicles sold in the USA are OBD2 compatible. You want to make sure your car/truck is in Closed Loop mode. This just means that the engine is warmed up to a nice 180-190*F so you’re seeing the true numbers from the sensors rather than the generic numbers from the computer.

First Things Firstīefore starting your engine diagnostics, you’re going to need a code reader, aka OBD2 Scanner. And while the data alone will not reveal the exact fix needed to sort out any problems with the motor, it will give you a bird’s eye view of the problem so you can pinpoint the actual fault.īut in order to do this, you’ll need to learn how to read live data from your OBD2 scan tool. This especially holds true for import European vehicles that demand a higher level scanning tool.īut now, even the most basic OBD2 scanner can not only scan and read diagnostic trouble codes (DTC). Learning how to interpret the live data from an OBD2 scanner is an excellent way to diagnose drivability problems in your ride.īefore cheap OBD2 scan tools became mainstream, mechanics had to purchase expensive factory scan tools. It doesn’t matter if you have a wired or wireless code reader, or if you prefer Wi-Fi over Bluetooth depending on your preferred device. Hey I’m Matt – Most DIY car fixes can be easily achieved using a basic OBD2 scan tool and today we’re going to help you understand how to read live data from OBD ii diagnostic scanners.
