Internal electronic failure
EMS ECU estimates the atmospheric
pressure values under the conditions of
Atmospheric pressure sensor faulty/
sensor not present with the help of Inlet
air flow, Inlet pressure and
temperature.~Manifold absolute
pressure circuit range /performance
fault detected by the ECU if the
estimated pressure is not within the
refference/specified range.
;
1.
Check 60A fuse connected to battery power supply is not blown
off and also check 10A fuse of ignittion power supply is not
blown off. Replace the fuse if found defective.
2.
Check the sensor connector for proper fitment; damage etc.,
ensure proper fitment of the connector with the sensor.
3.
Check sensor for oxidation rust, etc., if noticed clean the
deposits.
4.
Check for electrical continuity between ECU pins A58,A71 and
A04 to sensor connector pins 1,3 & 2. check continuity
between Ignition switch supply input to sensor connector pin 4
and rectify electrical discontinuity if noticed.Check ECU pins
and connector pins for damage/rust. In case of rust then clean
them and refit the connector.
5.
Check whether the AMF sensor signal pin A58 is Short circuited
to Battery or ground. If so, then rectify the wiring harness
connections.
6.
check whether the EMS ECU inlet temperature pin A04 is short
circuited to battery/Ground or open circuited because of
wrong connections of wiring harness, if so rectiify the wiring
harness connections to make them inline with circuit
schematics.
7.
Replace AMF sensor in case of any physical damage to sensor
or if the problem still persists.
8.
Replace the EMS ECU if the problem still perists.
9.
After rectification ensure the following before handing over to
customer.
a) Check the Air mass flow sensor reading at ignition key on
shows xx mg/st.
b) Air mass flow reads < xx mg/st when the engine is at idle.
c) Air mass flow reads > xx mg/st when the engine is at fly-
up.~
