A A B GO TO STEP 6 5. CHECK FUEL INJECTION SYSTEM (a) Check the fuel injection system
. HINT: If the problem area cannot be determined by checking the fuel injection system, proceed to the next step. NEXT GO TO STEP 9 6. CONFIRM LEARNED VALUE (a) Use the following formula to calculate the difference between the learned value from step *1 and the actual alcohol concentration in the fuel from step *2. HINT: | (Alcohol Density Estimate / 2) - (Alcohol Concentration in Fuel / 2) | < 10% Result RESULT PROCEED TO Difference is 10% or more A Difference is less than 10% B B GO TO STEP 9 7. CONFIRM ALCOHOL CONCENTRATION IN FUEL (a) Confirm the actual alcohol concentration in the fuel from step *2. Result RESULT PROCEED TO Alcohol concentration is 20% or less A Alcohol concentration is more than 20% B 3UR-FBE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0171,P017... |
