This happens when the sensor sends incorrect pressure readings to the electronic control module (ECM). Emission issues: The FTP sensor is a vital part of the EVAP system, so if it malfunctions, it can fail to detect vapor leaks. The vehicle will likely fail an emissions test since the EVAP system captures and controls fuel vapors.

The Electronic Control Module (ECM) regularly runs a leak test within the EVAP system using the fuel tank pressure sensor. A Failed Emissions Test or Smoke Test One of the main indicators of the P0442 code is a failed emission test or a smoke test.

This system traps and reroutes fuel vapor to the engine, reducing harmful emissions and improving fuel efficiency. What’s the purge valve’s function in the emissions system? The ECU (Electronic Control Unit) opens and closes the canister purge valve to control the vapor flow. How Long Should a Purge Valve Last?

Type of EGR valve : There are two types of EGR valves — electronic and mechanical. Electronic valves are usually more expensive to replace because they have more complex components and electronic controls. Repair complexity: In some cars, replacing an EGR valve takes less than an hour, but in others, it might be harder to reach.

In contrast, electronic regulators are more complex and costly, using sensors and the engine control unit (ECU) to regulate fuel pressure. Failed emissions test: A faulty regulator disrupts the air-fuel mixture in the engine, often resulting in too much fuel and not enough air.

Failed Emissions Test Incomplete combustion can result in higher levels of unburned hydrocarbons and carbon monoxide in the exhaust. These increased pollutants can lead to a failed emissions test. However, in modern vehicles equipped with electronic fuel injection, fuel delivery is handled by electric fuel pumps.
