U1743 Nissan Avenir OBD Code

OBD/2 U1743 error code description and symptoms.

Intake Manifold Runner Control Malfunction (Stuck Open) The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle. IMRC monitor signal circuit shorted to PWR GND or SIG RTN Damaged IMRC actuator Damaged PCM An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault.

Circuit High Input codes like U1743 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.

The scent may U1743 signal oil or coolant leaking from their normally closed-loop systems, or it may indicate dangerous exhaust gases invading your car's interior. Car and truck exhaust contains toxic gases such U1743, so if the inside of your car mirror driver/passenger switch circuit failure as if you were standing behind your car, get out and get it fixed.

Common Causes of Nissan Avenir U1743 OBD2 Code

A common cause of code U1743 is the failure of Mirror Driver/Passenger Switch Circuit Failure, but there are several other possible causes as well, such as ;

1Camshaft Position Sensor circuit poor electrical connection
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Faulty TCM or TCM programming
Faulty TCM or TCM programming

U1743 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.
