U2UA8 Nissan Micra OBD Code

OBD/2 U2UA8 error code description and symptoms.

Output Shaft Speed sensor circuit intermittent failure The output shaft speed sensor signal to the PCM is irregular or interrupted.
Harness connector not properly seated Harness intermittently shorted, or open Harness connector damaged OSS sensor damaged, or not installed properly Verify harness and connector integrity Verify OSS sensor proper installation.

Circuit High Input codes like U2UA8 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

For cylinder 11 injector circuit low check engine light is perhaps the most troubling of lights because it could mean so many different things, from you didn't screw the gas cap on tightly enough to look out for pistons flying through the hood and into the stratosphere. The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool.

After you instruct it to perform the scan, it speaks cylinder 11 injector circuit low with your car's computers to find out exactly what's prompting the light to turn on.

Common Causes of Nissan Micra U2UA8 OBD2 Code

A common cause of code U2UA8 is the failure of Cylinder 11 Injector Circuit Low, but there are several other possible causes as well, such as ;

Camshaft Position Sensor harness is open or shorted
Erratic camshaft position due to low oil pressure
EVAP canister or fuel tank leaks
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection

U2UA8 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.
