U282C Mercury Messenger OBD Code

OBD/2 U282C error code description and symptoms.

HO2S Sensor Circuit Malfunction (HO2S-11) During testing the HO2S Heaters are checked for opens/shorts and excessive current draw.
The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM.

As long as the throttle plate remains closed, the idling speed and quality is controlled by the PCM via the idle control valve, and as can be seen from the above it should be clear that idle control on a gasoline engine is a complex affair. For instance, if the engine is started in sub-zero temperatures, the PCM will command the idling control valve to allow less air to enter the engine to enrich the air/fuel mixture to create a condition which is roughly analogous to how chokes worked on carburetted engines to control idling in cold weather.

If your communication bus error (non scp) check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U282C and engine control unit are in charge of monitoring a bunch of different communication bus error (non scp), and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Mercury Messenger U282C OBD2 Code

A common cause of code U282C is the failure of Communication Bus Error (Non SCP), but there are several other possible causes as well, such as ;

Exhaust tube
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Intake Valve Timing Control Solenoid Valve harness is open or shorted
Variable Valve Timing (VVT) circuit is open or shorted

U282C is a kind of Network Trouble Code

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.
