DF046 Fault Symptoms :
If one of these reasons for DF046 code is occuring now you should check DF046 repair processes.
Now don't ask yourself; What should you do with DF046 code ?
The solution is here :
DF046 Possible Solution:
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
DF046 Code Meaning :
|For Engine||Ambient Air Temperature Sensor Circuit Low||Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector)||Ignition Coil A Primary/Secondary Circuit Malfunction|
The oxygen (02) sensors on your car measure the oxygen in the exhaust to determine how rich or lean the ratio of fuel and air are in the cylinders. Optimizing this mixture means better fuel economy and fewer exhaust emissions.
DF046 DescriptionDF046 engine trouble code is about Ignition Coil A Primary/Secondary Circuit Malfunction.
Main reason For DF046 CodeThe reason of DF046 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.
DF046 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
