Imported page. This page was converted from an archived copy of "Z31 EGR Control Solenoid" (Xenonzcar, fetched 2026-05-15). The conversion was mechanical, so tables, links and formatting may contain conversion artefacts. Compare against the archived copy if something looks wrong.

Z31 EGR Control Solenoid[edit]
In the Exhaust Gas Recirculation (EGR) System, some of the exhaust gas is returned to the combustion chamber to lower the flame temperature during combustion. This results in a reduction of nitrogen oxide (NOx) density in the exhaust gas.
When the EGR control valve is open, some of the exhaust gas is led from the exhaust manifold to the EGR tube. The exhaust gas is then regulated by the EGR valve and is introduced into the intake manifold.

Exhaust Gas Recirculation (EGR) System Operation[edit]
The signal from the ECCS control unit is sent to the EGR control solenoid valve, which cuts the vacuum line for the EGR control valve when any of the following conditions are met:
| Condition Present | EGR Control Solenoid Position | EGR System Operation |
|---|---|---|
| Engine Starting | On | Does Not Function |
| Throttle Valve Switch Open | ||
| Low Engine Temperature | ||
| Engine Speed Below 900 RPM Above 3200 RPM | ||
| Except Above | Off | Operates |
Diagnosis[edit]
