Honda Civic 2007 90km odometer Problem- Fuel consumption I have scanned my car and it shows STFT -9% along with below parameters.
- Coolant temp -> 64
- LTFT -> -7.03
- Oxygen sensor voltage -> .55v
- EGR Error -> 99 %
- Commandent EGR Duty -> 0%
- Commandent evaportaive purge -> 22%
- MAF flow rate - 2.7g/sec
I understand that if STFT is in negative then this is rich condition and it can impact fuel consumption widely. and the cause could be leak, fuel injector issue etc.
Any insights why my vehicle is not up to mart for mileage(fuel consumption) Pls let me know if I need to share more data about this.
