U0221 Engine Trouble Code
Meaning of U0221 engine trouble code is a kind of network trouble code and theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $240-$400 depending on the car, but that's usually the cost of parts because the labor is relatively simple.
U0221 Fault Symptoms :
If one of these reasons for U0221 code is occuring now you should check U0221 repair processes.
Now don't ask yourself; What should you do with U0221 code ?
The solution is here :
U0221 Possible Solution:
Power Steering Pressure (PSP) Switch Malfunction In Key On, Engine Off Self-Test, this DTC indicates the PSP input to the PCM is high. In Key On, Engine Running Self-Test, this DTC indicates that the PSP input did not change state. Steering wheel must be turned during Key On, Engine Running Self-Test PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged.
U0221 Code Meaning :
|OBD-II Diagnostic Network (U) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||Manifold Absolute Pressure/Barometric Pressure Circuit High Input||Turbocharger Boost Sensor A Circuit Low||Crankshaft Position Sensor A Circuit Low Input|
The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.
U0221 OBD-II Diagnostic Network (U) Trouble Code DescriptionU0221 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.
Main reason For U0221 CodeThe reason of U0221 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input.
U0221 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
