CIRCUIT DESCRIPTION
The EGR system recirculates exhaust gas, which is controlled to the proper quantity to suit the
driving conditions, into the intake air mixture to slow down combustion, reduce the combustion
temperature and reduces NOx emissions. The amount of EGR is regulated by the EGR vacuum
modulator according to the engine load.
If even one of the following conditions is fulfilled,
the VSV is turned ON by a signal from the ECM.
This results in atmospheric air acting on the EGR
valve, closing the EGR valve and shutting off the
exhaust gas (EGR cut±OFF).
Under the following conditions, EGR is cut to
maintain driveability.
wEngine coolant temp. below 60C (140F).
wDuring deceleration (throttle valve closed).
wLight engine load (amount of intake air very
small).
wEngine speed over 4,400 rpm.
wEngine racing.
EG R gas temp. is 70C (158F) or below for 50
sec. under conditions (a) and (b).
(2 trip detection logic) *
(a) Engine coolant temp.: 80C (176F) or more.
(b) EGR operation possible (EX. A/T in 3rd speed
(5th for M/T), 55 ± 60 mph (88 ± 96 km/h),
Flat road).wOpen in EGR gas temp. sensor circuit.
wShort in VSV circuit for EGR.
wEGR hose disconnected, valve stuck.
wClogged EGR gas passage.

Setting the test mode.
(1) Turn ignition switch OFF.
(2) Connect terminals TE2 and E1 of DLC2.
(3) Turn ignition switch ON.
(For checking terminal IDL, disconnect the
vacuum hose from the throttle body, then
apply vacuum to the throttle opener (See page
EG1±204).)
(For checking terminal A/C, start the engine.)
(4) Connect terminals TE1 and E1 of DLC2.
*: Before the STA signal is input (ST is not ON),
diagnostic trouble code 43 is also output. Check output condition of diagnostic trouble code 51.

amplifier connector and body ground.(1) Disconnect throttle position sensor connec±
tor.
(2) Disconnect the vacuum hose from the throt±
tle body, then apply vacuum to the throttle
opener (See page EG1±204).
Measure resistance between terminals 2 (IDL)
and 1(E2) of throttle position sensor connector.
Check for open and short in harness and connector between
engine control module and A/C amplifier (See page IN±31). Disconnect A/C amplifier connector, check voltage between
terminal AC2 of A/C amplifier connector and body ground.

(1) T±Rivet with f6.4 mm:
Using a ponch with f5 mm, stamp out the mandrel.
(2) Put tape around the drill blade 5 mm (0.20 in.) from
the tip or insert a vacuum hose.
NOTE: Use of tape or a vacuum hose prevents dam-
age to the rivet hole.
(3) Attach the drill blade or a rivet cutter to the drill.
(4) Gently and vertically put the drill to the rivet, and cut
the rivets flange.
NOTE:
While upward drilling, wear a protective glasses.
If a drill is strongly pushed deeply in to a rivet, the
rivet can't be cut as it spins together with the drill.
Prizing the hole with a drill can lead to damage to
the rivet hole or the breaking of the rivet cutter.
Take care as the cut rivet is hot.
(5) Aluminum±Rivet and Waterproof±Rivet with f4.8 mm
or f6.0 mm:
Even if flange is taken off, continue drilling and push
out remaining fragments with the drill.
(6) Steel±Rivet:
If the flange is taken off, stop drilling and, pull out the
remaining fragments with a pliers.
(7) T±Rivet with f6.4 mm:
If the flange is taken off, stop drilling and push out the
remaining fragments with a ponch with f5 mm or pull
out the remaining fragments with pliers.
