3.
Periode ③ is in W.O.T and the voltage there is 4.3 V,and MAP sensor voltage is about 4.3 V.
The Manifold Absolute Pressure(MAP) sensor measures the change of pressure in the intake manifold. The pressure of intake manifold is changed as variable engine running condition and converted into voltage and then it is monitored by the ECM.
The ECM sets DTC P0107 if the ECM detects signal voltage lower than the possible range of a properly operating MAP sensor.
Item | Detecting Condition | Possible cause |
Monitoring Strategy | ● Signal check, low Rationality check | ● Open circuit in power line ● Short between signal and ground line ● Bad MAP sensor ● Bad ECM ● Clogged air cleaner ● Leakage in intake system |
Threshold value | ● Air mass flow > Max Threshold map, f(eng,speed,TPS) | |
Enable Conditions | ● 0.5sec after engine start > 11V | |
Diagnostic Time | ● 2 sec | |
MIL on condition | ● 2 driving cycle |
If any codes relating to TPS are present,do all repairs associated with before proceeding this troubleshooting procedure.
Specification
idle : 0.3~0.9V
full : 4.0~4.4V
When checking TPS waveform,it is strongly recommended to examine waveform with MAP sensor waveform.
Peride ① is the voltage of MAP in idling and 0.8~1.2 V,and there must be a little fluctuation in waveform.
In case there is no fluctuation
Possible cause : Deteriorated MAP sensor or some foreign material in MAP sensor.
The voltage in Periode ② is 0.3~1.0V in average.
Periode ③ is in W.O.T and the voltage there is 4.3 V,and MAP sensor voltage is about 4.3 V.

In case there is no symptom and wrong data but DTC is shown
In case there is no symptom and wrong data but DTC is shown
The problem may be intermittent so slightly shake the connector and harness vertically and horizontally to check if there is any data changes
If the data changes normally, the problem was intermittent so erase DTC and verify the same DTC reoccure.
Go to "Terminal and Connector inspection" procedure.
In case there is symptom and wrong data with DTC
Check open,short or connector’s connection for MAP.
Check the deterioration of MAP performance.
Go to "Circuit Inspection" procedure.
