bigah Posted September 24, 2007 Report Share Posted September 24, 2007 I got these codes that wont go away P0178 Fuel Compensation Sensor Circuit Low Input DTC Pending codes P0178 Fuel compensation sensor circuit low input P0101 MAF or VAF CKT Range/Perf I cleaned my MAF and checked connections and checked for leaks. What does Pending codes mean? Does it mean both pending codes are caused by my Fuel compensation sensor? The reason I havent replaced the Fuel Compensation Sensor is because I am never going to run E85 and its a $500. I dont know if I can get by with it or not. Does anyone have any ideas or solutions for me? Any help will be appreciated and thank you in advance. Quote Link to comment Share on other sites More sharing options...
misterp Posted September 24, 2007 Report Share Posted September 24, 2007 If you've got a flex-fuel truck then it's new enough to take to the dealer and warranty it. Mr. P. Quote Link to comment Share on other sites More sharing options...

misterp Posted September 24, 2007 Report Share Posted September 24, 2007 Maybe check the wrecking yards for a sensor from a recently totalled truck? Quote Link to comment Share on other sites More sharing options...
