U3459 Peugeot Quadricycle OBD Code

OBD/2 U3459 error code description and symptoms.

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.

As the engine heats up and combustion becomes easier and more complete, the PCM will command the idling control valve to increase the amount of air entering the engine to suit the changing conditions. However, when the load on the engine changes, say, when some electrical consumers or other systems are either turned on or off, the PCM adapts the signal voltage to the idle control valve to ensure that the idling speed remains stable, and at the RPM specified by the manufacturer.

For fuel pulse in range but lower than expected 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.

After you instruct it to perform the scan, it speaks fuel pulse in range but lower than expected with your car's computers to find out exactly what's prompting the light to turn on.

Common Causes of Peugeot Quadricycle U3459 OBD2 Code

A common cause of code U3459 is the failure of Fuel Pulse In Range But Lower Than Expected, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Camshaft Position Sensor harness is open or shorted
Faulty Intake Valve Timing Control Solenoid Valve
EVAP canister or fuel tank leaks

U3459 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.
