P0042 Engine Trouble Code
Meaning of P0042 engine trouble code is a kind of powertrain trouble code and P0042 if your catalytic convertor fails completely, you eventually won't be able to keep the car running. Your gas mileage will also be terrible, so you should try and fix it as soon as you can. Unfortunately, the average replacement cost is around $2,140 and you can't do it yourself unless you're an experienced mechanic.
P0042 Fault Symptoms :
If one of these reasons for P0042 code is occuring now you should check P0042 repair processes.
Now don't ask yourself; What should you do with P0042 code ?
The solution is here :
P0042 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.
P0042 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||Ambient Air Temperature Sensor Circuit Low||Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector)||Glow Plug/Heater Circuit 'A' Malfunction|
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
P0042 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0042 OBD-II Trouble Code Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches t P0042 code.
Main reason For P0042 CodeThe reason of P0042 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.
Parts or components should not be replaced with reference to only a P0042 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
