When you start a cold engine, it initially operates in an open loop mode. In this open loop operation, the engine typically runs with a richer air-fuel mixture. This is a standard procedure designed to quickly warm up the engine and catalytic converter to their optimal operating temperatures.
The Non-Methane Hydrocarbon (NMHC) Catalytic Converter Monitor
The Non-Methane Hydrocarbon catalytic converter monitor is a specific type of catalytic converter monitor. Its primary function is to help reduce residual non-methane hydrocarbons (NMHC) from the exhaust stream after the combustion process. To achieve this, the materials within the catalytic converter react with the exhaust gases, converting NMHC into less harmful compounds. The vehicle’s computer (ECU or PCM) assesses the efficiency of the catalytic converter by monitoring the amount of NMHC present in the exhaust flow. This monitor also verifies if there’s sufficient temperature to support the regeneration of the particulate matter (PM) filter in diesel applications.
It’s important to note that the NMHC monitor is generally found in “compression ignition” vehicles, which refers to diesel engines. The NMHC monitor is a “Two-Trip Monitor.” This means that if a fault is detected during the first drive cycle (trip), the computer will temporarily store the fault as a pending code in its memory. At this stage, the Malfunction Indicator Lamp (MIL), commonly known as the check engine light, is not activated. However, if the same fault is detected again during a subsequent drive cycle (second trip), the computer will then illuminate the MIL and store the diagnostic trouble code (DTC) in long-term memory.
For those looking to pre-test their vehicle before an emissions inspection, tools like the Innova 3220mx code reader are highly recommended.
Displays All 15 Monitors on Screen
The Innova 3220mx provides readings for up to 15 Inspection/Maintenance (IM) Monitors in under a minute, thanks to its patented all-in-one screen. It also features a color-coded system – a traffic light indicator – to quickly assess your vehicle’s system status. A green light indicates the system is ready and should pass inspection without issues. A red or yellow light signals potential problems that could lead to failing an emissions test.
