Low.
M
1. MIL is ON
2. EGR is disabled
3. Injector learning strategy (MDP
Updating) is deactivated.
4. Probable loss of power and black smoke.
This DTC gets logged if
inlet- air temperature read
by the AMF sensor is less
than the lower threshold.
1. Check for Reference
voltage 1 fault or If P0110 is
present.
2. Check sensor connections
for rust dirt etc.
3. Check sensor
characteristics (measure
voltage and resistance at
sensor terminals).
4. Check Electrical continuity.
5. Check ECU.
1. Check for Reference voltage 1 fault (P0642;
P0643) if present; Follow Reference voltage
1(sensor supply voltage 1) check and rectification
Procedure; to correct this fault before proceeding
further.
2. Check sensor connections for rust, dirt etc.; if
noticed clean the sensor connections and ensure
proper fitment.
3. Check sensor characteristics (measure voltage
and resistance at sensor terminals); Sensor voltage
should be 5 V and resistance as given in
specifications. Replace sensor if found faulty
4.Check whether the EMS ecu pin 36 is Short
circuited to ground. Rectify the wiring harness
connections according to circuit schematics if any
short circuits are found.
5. Check ECU; Replace ECU; if problem still
persists.
6. After rectification ensure the following checks
before handing over the vehicle to customer.
a) AMF sensor reads 636 mg/st at key on
condition.
b) When the engine is at idle AMF sensor reads <
700mg/st.
c) When the engine is at fly-up AMF sensor reads
> 800 mg/st.
7. After rectification if possible carry out following
check
Soak the vehicle for more than 12 hrs.
(preferably overnight)
Then check if all the system temperature values
(coolant; fuel; inlet air) are close to each other.
N Y
12 P1110
AMF sensor
(inlet air temp) -
AD fault.
H MIL is ON.
This DTC gets logged due
to fault registered in the AD
convertor in the ECU.
1. Check for Reference
voltage1 fault or If P1100 is
present.
2. Check sensor connections
for rust dirt etc.
3. Check sensor
characteristics (measure
voltage and resistance at
sensor terminals) 4. Check
Electrical continuity.
5. Check ECU.
1. Check by erasing the fault once or twice.
2. If the problem keeps on repeating replace ECU N Y
