4JH1 ENGINE DRIVEABILITY AND EMISSIONS

Circuit Description

The ECM is calculates an injection quantity and an
injection timing using the various sensors (crankshaft
position sensor, camshaft position sensor, engine
coolant temperature sensor, etc.). The timing control
valve (TCV) operation performs an injection timing
decision.
The TCV performs as a variable throttle, using the rapid
opening and closing cycle of the valve needle in the
TCV.
The TCV is assembled in the injection pump. The signal
of desired injection timing and actual injection timing are
exchanged via the CAN-bus between the PSG and
ECM.
If the timer position is out of tolerance (deviation or
fluctuation), DTC P0216 will be stored.

Diagnostic Aids

An intermittent may be caused by the following:

• Poor connections.

• Misrouted harness.

• Rubbed through wire insulation.

• Broken wire inside the insulation.

• Insufficient air bleeding of fuel line.
Check for the following conditions:

• Insufficient air bleeding of fuel line inside, clogged

fuel filter or pinched fuel pipe/hose may cause the
DTC store or improper engine performance.

• Poor connection at ECM and PSG-Inspect harness

connectors for backed out terminals, improper
mating, broken locks, improperly formed or damaged
terminals, and poor terminal to wire connection.

• Damaged harness-Inspect the wiring harness for

damage. If the harness appears to be OK, observe
the “Actual Injection Start” display on the Tech2 while
moving connectors and wiring harness related to the
sensor.

Visually/physically inspect for the following conditions.

• Restrict fuel supply system. Check for a pinched

fuel hose/pipe.

• Check for a condition that causes fuel waxing or

icing, such as the customer is using an incorrect
fuel type in winter season or water mixed with the
fuel.

If a problem is found, repair as necessary.
