VCT Monitor

Variable Cam Timing System Monitor
VCT Hardware

Variable Cam Timing (VCT) enables rotation of the camshaft(s) relative to the crankshaft (phase-shifting)
as a function of engine operating conditions. Intake Only (phase-shifting only the intake cam) is used in
the AML application.

VCT is used primarily to increase internal residua l dilution at part throttle to reduce NOx, and to
improve fuel economy. With Intake Only VCT, the in take camshaft is advanced at part throttle and WOT
(at low to mid-range engine speeds) to open the in take valve earlier for increased residual dilution and
close the intake valve earlier in the compression stroke for increased power. When the engine is cold,
opening the intake valve earlier warms the charge which improves fuel vaporization for less HC
emissions; when the engine is warm, the residua l burned gasses limit peak combustion temperature to
reduce NOx formation.

The VCT system hardware consists of a contro l solenoid and a pulse ring on the camshaft. The PCM
calculates relative cam position using the CMP input to process variable reluctance sensor pulses coming
from the pulse ring mounted on the camshaft. Each pul se wheel has N + 1 teeth where N = the number of
cylinders per bank. The N equally spaced teeth are used for cam phasing; the remaining tooth is used to
determine cylinder # 1 position. Relative cam position is calculated by measuring the time between the
rising edge of profile ignition pickup (PIP ) and the falling edges of the VCT pulses.

VCT Diagnostic

The PCM continually calculates a cam position error value based on the difference between the desired
and actual position and uses this information to cal culate a commanded duty cycle for the VCT solenoid
valve. When energized, engine oil is allowed to flow to the VCT unit thereby advancing and retarding cam
timing. The VCT logic calculates the instantaneous va riance in actual cam position (the squared difference
between actual cam position and commanded cam position), then calculates the long term variance using a
rolling average filter (Exponentially Weighted Moving Average).
If the VCT system is stuck or operates with an consta nt error relative to the target position, the monitor
will detect a variance which will quickly accumulate. There are three variance indices that monitor cam
variance in the retard direction, the advance directi on, and for V engines, the difference between banks. If
any variance index is greater than the malfunction threshold, a VCT target error malfunction will be
indicated (P0011, P0012 Bank 1, P0021, P0022 Bank 2).

The VCT solenoid output driver in the PCM is check ed electrically for open circuit and shorts (P0010
Bank 1, P0020 Bank 2).

Comprehensive Component Monitor - Engine

General Inputs

Analog inputs such as Ambient Air Temperature (P0072, P0073), Intake Air Temperature (P0112, P0113),
Engine Coolant Temperature (P0117, P0118), Cylinder Head Temperature (P1289, P1290), Mass Air Flow
(P0102, P0103) and Manifold Absolute Pressure (P0107, P0108) are checked for opens, shorts, or out-of-
range values by monitoring the analog -to-digital (A/D) input voltage.

Analog Sensor Check Operation:
DTCs P0072, P0073, P0112, P0113, P0117, P0118, P0102, P0103, P0107, P0108,
P1289, P1290
Monitor execution continuous
Monitor Sequence none
Monitoring Duration 5 seconds to register a malfunction

Typical analog sensor check malfunction thresholds:
Voltage < 0.20 volts or voltage > 4.80 volts

On Vehicles fitted with Cylinder Head Temperature (CHT ) Sensors, 'Fail Safe Cooling' can be applied if
the cylinder head temperature is too high. The P1299 DTC will be set under these conditions.

Loss of Keep Alive Memory (KAM) power (a separate wire feeding the PCM) results in a P1633 DTC and
immediate MIL illumination.

Loss or corruption of the Vehicle Identification (VID) Block in the PCM results in a P1639 DTC and
immediate MIL illumination.


Ignition

Electronic Ignition systems (Electronic Distributorless Ignition System - EDIS or Coil on Plug - COP)
systems are used on all applications.

The EDIS system, located in the PCM, processes the 36 (or 40) tooth crankshaft position signal to
generate a low data rate PIP signal to control a 4 or 6 terminal 'double-ended' coil pack. The 'double ended'
coils fire a pair of spark plugs simultaneously - one is on its compression stroke, the other on its exhaust
stroke. The COP system also uses the EDIS system in the same way as described above, however each
sparkplug has it’s own coil which is fired only once on the compression stroke.

The ignition system is checked by monitoring three ignition signals during normal vehicle operation:

Profile Ignition Pickup (CKP, commonly known as PIP), the timing reference signal derived from the crankshaft 36-tooth wheel and processed by the EDIS system. PIP is a 50% duty cycle, square
wave signal that has a rising edge at 10 ° BTDC.

Camshaft IDentification (CMP, commonly known at CID), a signal derived from the camshaft to identify the #1 cylinder

AML EOBD System Operation Summary

Ignition Diagnostic Monitor (IDM), a signal which indicates that the primary side of the coil has
fired. This signal is received as a digital pulsewidth signal from the EDIS system which process
the high voltage flyback signal from the primary side coil.

The relationship between successive PIP events is ev aluated to determine whether the PIP signal is
rational. Too large a change in 3 successive PIP indicates a missing or noisy PIP signal (P0320 or P0321).
Then the CMP edge count is compared to the PIP e dge count. If the proper ratio of CMP events to PIP
events is not being maintained (for example, 1 CMP e dge for every 8 PIP edges for an 8-cylinder engine),
it indicates a missing or noisy CMP signal (P0340). Finally, the relationship between IDM edges and PIP
edges is evaluated. If there is not an IDM edge (co il firing) for every PIP edge (commanded spark event),
the PCM will look for a pattern of failed IDM events to determine which ignition coil has failed circuit
continuity (P0351-56).

Ignition System Check Operation:
DTCs P0320 / P0321 (CKP), P0340 (CMP), P0351 - P0358 (Coil Primary)
Monitor execution continuous
Monitor Sequence none
Monitoring Duration < 5 seconds

Typical ignition check entry conditions : Minimum Maximum
Engine RPM for CKP, CMP 200 rpm
Engine RPM for coil primary 200 rpm

Typical ignition check malfunction thresholds:
For PIP : Time between PIP edges : > 350 milliseconds
Ratio of current PIP period to last two periods : < 0.75 > 1.75
For CMP : Ratio of PIP events to CMP events: 4:1, 6:1, 8:1 or 10:1 based on engine cyl.
For coils : Ratio of PIP events to IDM events: 1:1


General Outputs

The Fuel Injectors are checked electrically for open and short circuit (P0201 to P0208).

The Idle Air Control (IAC) solenoid is checked electrically for open and shorts (P1504).

The Purge Solenoid or Vapour Management Valve output circuit is checked for opens and shorts (P0443).
