I just ran a CanOBD2 code reader on my '05 Chevy Blazer and got a code back refering to a MASS or VOLUME CIRCUIT RANGE PERFORMANCE PROBLEM. What should I do to fix this problem?
Country: CanadaMake: ChevroletModel: Blazer 4x4 (Mid Size)Year: 2005Engine: 4.3L vortec V6 with A/C
Nothing, But I've lost power and can't get up pass 105 km/h before the motor revs out. Thanks for any help.
Can you give me the actual "p-code" associated with this description?
Ok- the P0101 is a fairly straight forward code pointing to a fault in the Mass Air Flow sensor. A faulty MAF will definitely cause the symptoms you are describing. Check the electrical connector for any loose or broken wires. Check that the Air Filter is not excessively dirty and that there is no dirt/debirs in the air filter housing. Make sure there are no air leaks in the air cleaner housing or duct work. If the visual inspection checks ok, suspect a faulty MAF, and replacing the sensor should solve the problem.
