Mass Air Flow (MAF) Sensor Intermittent The MAF sensor circuit is monitored by the PCM for sudden voltage (or air flow) input change through the comprehensive component monitor (CCM). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

One example of this would be when an automatic vehicle in placed in gear. To prevent the added drag from the torque converter and transmission from reducing the idling speed, the PCM will command the idle control valve to allow more air to enter the engine, while at the same time, adjusting the injector pulse width to inject more fuel to suit the increased amount of air. Note that the idle air control valve is closed by the PCM when the throttle plate is opened to prevent excess air from entering the engine.

The on-board diagnostics system U222D and engine control unit are in charge of monitoring a bunch of different power sliding door on/off switch open circuit, and if they get a reading that's a little out of whack, up pops the check engine light.

U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.

Common Causes of U222D

A common cause of code U222D is the failure of Power Sliding Door On/Off Switch Open Circuit, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Damaged ECM
Faulty ignition coil (s)
Fuel filler cap remains open or fails to close
