Components

PSP switch

The PSP switch is located in the power steering line.

The PSP switch registers pressure in the line between the power steering pump and steering
gear. This switch opens on reaching a defined pressure.

KS

In conjunction with the PCM, the KS monitors the combustion process and regulates the
injection period so that predetermined volumes of fuel are injected into the cylinders at
every operating cycle.

By constantly measuring the amount of knock present and adjusting the injection period,
the emission values of the engine remain stable.

IMRC actuator

The IMRC meters the amount of air flow air velocity in the intake manifold. At low engine
speeds the IMRC is fully closed, keeping air flow velocity high, while at low volume. As the

engine speed increases, the IMRC opens to allow for more air to enter the intake manifold.

EOP sensor

The EOP sensor is located in the oil filter housing. The EOP is connected to the instrument
cluster and is not directly part of the electronic engine control system. The EOP sensor
registers engine oil pressure. The sensor opens when a defined oil pressure is reached and
the engine oil pressure warning light is illuminated on the instrument cluster.

CKP sensor

The CKP sensor is an inductive pulse generator which scans 36-1 cast protrusions on the
flywheel. Minus one means that one of the cast protrusions is missing and this gap is
located at 90 degrees before top dead centre. This gap is used by the PCM as a reference
for crankshaft position.

The CKP sensor uses the Hall effect principle.

HO2S

The HO2S is a linear characteristic type sensor, installed forward of the catalytic converter.
The PCM uses this as it's primary sensor to measure the oxygen content of the exhaust
gasses within the exhaust system to provide closed-loop fuelling control.
