The Intake Manifold Runner Control (IMRC) is a syst em which uses dual intake runners to supply air to
each cylinder. The secondary runners are normally closed, but the PCM opens them under high rpm
conditions when the driver is demanding additiona l power from the engine. The IMRC system can be
actuated using an electric motor or a vacuum moto r. The IMRC system is functionally checked by
monitoring the runner control plates using switches. If the actual position of the runner control plates does
not match the commanded position, a malfunction of the IMRC system is indicated (P1518, P1519).

The Swirl Control Valve (SCV) is a system which uses di fferent regions of the Intake plenum to influence
the pattern of the airflow into the combustion chamber.

It is important to note that this functional / rationality check may or may not be a MIL Code. This is
dependent on whether the EOBD Thresholds are exceeded.

IMRC / SCV System Check Operation:
DTCs P1520 (IMRC input switch electrical check)
P1518, P 1519 (IMRC stuck open functional check)
Monitor execution continuous
Monitor Sequence none
Monitoring Duration 5 seconds

Typical IMRC functional check malfunction thresholds
IMRC plates do not match commanded position (functional)
IMRC switches open/shorted (electrical)


Camshaft Position Control (also known as Variable Cam Ti ming) is a system which is able to advance and
retard camshaft timing relative to the crankshaft. Th is phasing is controlled by a duty-cycled output. The
output driver is checked electrically for opens and s horts (P1380). The system is checked functionally by
monitoring the closed loop phase control correction. If the proper phasing cannot be maintained and the
system has an advance or retard error greater than the malfunction threshold, a CPC control malfunction is
indicated (P1381, P1383).

It is important to note that the functional / rationality checks may or may not be a MIL Code. This is
dependent on whether the EOBD Thresholds are exceeded.

Camshaft Position Control System Check Operation:
DTCs P1380 (CPC output electrical check)
P1381 (CPC timing over-advanced functional check)
P1383 (CPC timing over-retarded functional check)
Monitor execution continuous
Monitor Sequence ECT > 150 oF
Monitoring Duration 5 seconds

Typical CPC functional check malfunction thresholds:
timing over-advanced/over-retard ed by > 10 crankshaft degrees

Engine CCM temporary disablement conditions ( other than entry requirements ) :
None, except CPC does not operate (and is therefore not checked) if ACT/IAT, ECT/CHT, MAF/MAP or
TP sensors are malfunctioning.
