wheel' and the excess pressure will be dissipated through the
expansion valve. When the pressure drops below 27.6 bar,
the safety valve will close again and the compressor will be
operative.
The terms ‘high’ and ‘low’ pressure (or side) refer to the
pressure differential between the compressor and expansion
valve ports. This differential is critical to system fault
diagnosis and efficiency checks.
The high side starts at the compressor and includes the
trinary switch, condenser, receiver drier and expansion
valve.
The low side starts at the expansion valve outlet and includes
the evaporator and all connectio ns back to the compressor.
The trinary switch (6) monitors system pressure between the
compressor and condenser. If the pressure rises above 30
bar or falls below 2 bar the compressor clutch is
de-energised to prevent damage to system components.

Differential Pressure Feedback EGR System Monitor

Where a vacuum driven EGR valve is used on the base application, the EGR System Monitor will consist
of a series of electrical and functional tests for the various aspects of system operation. First, the
Differential Pressure Feedback EGR (DPFE) sensor input circuit is checked for out of range values (P1400
P1401). The Electronic Vacuum Regulator (EVR) output circuit is checked for opens and shorts (P1409).


EGR Electrical Check Operation:
DTCs P1400, P1401, P1409
Monitor execution continuous, during EGR monitor
Monitor Sequence none
Monitoring Duration 4 seconds to register a malfunction

Typical EGR electrical check entry conditions:
EGR system enabled

Typical EGR electrical check malfunction thresholds:
DPFE sensor outside voltage: > 4.96 volts, < 0.195 volts
EVR solenoid smart driver status indicates open/short



The differential pressure indicated by the DPFE sensor is also checked at idle with zero requested EGR
flow to perform the high flow check. If the differen tial pressure exceeds a calibratable limit, it indicates a
stuck open EGR valve or debris temporar ily lodged under the EGR valve seat (P0402).

EGR Stuck open Check Operation:
DTCs P0402
Monitor execution once per driving cycle
Monitor Sequence Done after P1400 and P1401 tests
Sensors OK CPS, ECT, IAT, MAF, MAP, TP
Monitoring Duration 10 seconds to register a malfunction

Typical EGR stuck open check entry conditions : Minimum Maximum
EVR Duty Cycle (EGR commanded off) 0% 0%
Engine RPM (after EGR enabled) at idle at idle

Typical EGR stuck open check malfunction thresholds:
DPFE sensor voltage at idle versus engine-off signal: > 0.6 volts

After the vehicle is started, during vehicle acceleration, the differential pressure indicated by the DPFE
sensor at zero EGR flow is checked to ensure that both hoses to the DPFE sensor are connected. Under
this condition, the differential pressure should be zer o. If the differential pressure indicated by the DPFE
sensor exceeds a maximum threshold or falls below a minimum threshold, an upstream or downstream
DPFE hose malfunction is indicated (P1405 P1406).

EGR Hose Check Operation:
DTCs P1405, P1406
Monitor execution once per driving cycle
Monitor Sequence Done after P0402 test
Sensors OK MAF, MAP
Monitoring Duration 2 seconds to register a malfunction

Typical EGR hose check entry conditions : Minimum Maximum
EVR duty Cycle (EGR commanded off) 0% 0%
Mass Air Flow 8 lb/min
Inferred exhaust back pressure 13 in H2O

Typical EGR hose check malfunction thresholds:
DPFE sensor voltage: < -7 in H2O, > 7 in H2O


After the vehicle has warmed up and normal EGR rates are being commanded by the PCM, the low flow
check is performed. Since the EGR system is a closed loop system, the EGR system will deliver the
requested EGR flow as long as it has the capacity to do so. If the EVR duty cycle is very high (greater
than 80% duty cycle), the differential pressure indicated by the DPFE sensor is evaluated to determine the
amount of EGR system restriction. If the differential pr essure is below a calibratable threshold, a low flow
malfunction in indicated (P0401).

EGR Flow Check Operation:
DTCs P0401
Monitor execution once per driving cycle
Monitor Sequence Done after P1405 and P1406 tests
Sensors OK CPS, ECT, IAT, MAF, MAP, TP
Monitoring Duration minimum 70 seconds to register a malfunction

Typical EGR flow check entry conditions: Minimum Maximum
EVR Duty Cycle 80% 100%
Engine RPM 2500 rpm
Mass Air Flow Rate of Change 6% prog. loop
Inferred manifold vacuum 6 in Hg 10 in Hg

Typical EGR flow check malfunction thresholds:
DPFE sensor voltage: < 6 in H2O

EGR Monitor temporary disablement conditions ( other than entry requirements ) :
Non-operational when base feature disabled, including matching base feature temperature disablement.
Low Barometric Pressure Conditions.
Reporting of faults suppressed below 32° F to prevent mis-diagnosis due to ice. Monitor is still operational
and continues to check, reporting any faults when temperature > 32 °F.

1) "Continuous" under the "Time Required" column indicates that the specified test cycles at a frequency greater than once every 0.5 seconds whenever the
test entry conditions are met.
2) "Once per driving cycle" under the "Time Required" column indicates that the specified test will complete during the first 2 bags of an FTP as well as under
the test entr
y conditions specified, on the road.
3)All test entry condition parameters are measured instantaneously unless otherwise indicated.
p) If a 6 hour soak is met, some strategies will not require another continuous 6 hour soak if the customer performs a brief key-off. This has been put into
effect to improve evap monitor completion frequency.
q) Some strategies will have the ability to base evap monitor soak length on the CARB cold soak criteria which consists of an ECT range and ACT/ECT
differential.
r) A minimum soak time has been added to CARB's cold soak criteria (footnote q) to allow calibrators to set a minimum soak time if longer soak times are
n
eeded than given by the ACT/ECT-based CARB soak criteria.
a) A pending code will be stored after a malfunction has been detected on one driving cycle; a DTC will be stored after the same malfunction has been detected on the second consecutive driving cycle. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been
extinguished for the DTC.b) A DTC will be stored immediately upon detection of a malfunction. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for the DTC.k) A DTC will be stored after a malfunction has been detected on one drive cycle.The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for that DTC.l) A DTC will be stored after a malfunction has been detected on six consecutive drive cycles. The DTC will be erased after 40 warm-up cycles with no malfunction present, after the MIL has been extinguished for that DTC.o)For intake air temperatures below 20 deg F, no DTC will set for indicated AIR malfunction.
s) A DTC will be stored after an evaporative system leak has been detected and the refueling debounce check has been completed on the subsequent
driving cycle
c)The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles.
The MIL will be extinguished after three consecutive driving cycles where the monitor was run without a malfunction.d)The MIL will blink immediately upon detection of a misfire rate that exceeds the catalyst damage threshold, regardless of whether fuel is shut off or not.
If the misfire rate drops below the catalyst damage threshold, the MIL will stay on solidly.
The MIL will be extinguished after three consecutive drive cycles where similar conditions have been seen without the malfunction.e)The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles.
The MIL will be extinguished after three consecutive drive cycles where similar conditions have been seen without the malfunction.f)For intake air temperatures below 32 deg F, the MIL will not illuminate for the indicated EGR DTCs.
For barometric pressures below 22.5"Hg, the MIL will not illuminate for the indicated EGR DTCs.
For intake air temperatures below 20 deg F, the MIL will not illuminate for the indicated AIR DTCs.
This prevents false MIL illumination due to ice in the EGR hoses or AIR switching valve(s).g)This monitor employs EWMA.
The MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles after DTCs have been erased or Keep Alive Memory
h
as been erased (battery disconnect).
The MIL will be illuminated after a malfunction has been detected on up to six consecutive driving cycles during subsequent, "normal" customer driving.
The MIL will be extinguished after up to six consecutive driving cycles without a malfunction.
h) Some automatic transmission monitors are demonstrated following the USCAR Abbreviated On-Board Diagnostic Test Procedure for Vehicles Equipped
wi
th Automatic Transmissions.
This prevents false MIL illumination on this non-turbine speed sensor transmission application.
i)The MIL will be illuminated after a malfunction has been detected on the first driving cycle.
The MIL will be extinguished after three consecutive driving cycles where the monitor was run without a malfunction.j)A DTC will be set after a malfunction has been detected on two consecutive driving cycles.
m) MIL will be illuminated after a malfunction has been detected on two consecutive driving cycles. MIL will be extinguished after the monitor has run
wi
thout a malfunction (same or subsequent drive cycle).
n) A check cap light will be illuminated after a malfunction has been detected on one driving cycle. The check cap light will be extinguished after the monitor
