Trouble Ticket Help Requests for DTC P0151
Help Request Posted
2001 Chevrolet Suburban 1500 5.3L Cuts out, MIL Lamp on VIN: 3GNFK16T71
P0151: Heated Oxygen Sensor (Bank 2 Sensor 1) Circuit Low Voltage. This suburban will accelerate fine up to 25 miles per hour, then cuts out. At 25 mph the RPMs drop and will not accelerate. If I feather the throttle lightly I can get it up to 60 mph. Any ideas on what this may be? Thanks
