It is considered generic because it applies to all makes and models of vehicles, although specific repair steps may be different depending on your car model.
SymptomsSymptoms of a U016B diagnostic trouble code may include:
Possible Causes :
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness. Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1. Also, if a oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed. Once located, visually inspect the connectors and wiring. Look for rubbing, scraping, bare wires, worn spots or melted plastic connectors.
Diagnostic trouble code U016B is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.
Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before U016B.
Fortunately, U016B is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
