B0181 Engine Trouble Code
Meaning of B0181 engine trouble code is : B0181 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 $2,000 and you can't do it yourself unless you're an experienced mechanic.
B0181 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.
B0181 Code Meaning :
|OBD-II Diagnostic Body (B) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||Fuel Rail/System Pressure - Too High||Ignition/Distributor Engine Speed Input Circuit Malfunction||Crankshaft Position Sensor A Circuit Low Input|
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.
B0181 OBD-II Diagnostic Body (B) Trouble Code DescriptionB0181 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.
Reason For B0181 CodeThe reason of B0181 OBD-II Engine Trouble Code is Fuel Rail/System Pressure - Too High.
B0181 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.
