Section 05 ENGINE MANAGEMENT (2-TEC)
Subsection 02 (DIAGNOSTIC PROCEDURE)
TPS (Throttle Position Sensor) Faults
Faults which are reported in B.U.D.S. fall into two groups TPS faults and adaption faults. These are dis-
played on the B.U.D.S. system as TPS OUT OF RANGE and TPS ADAPTION FAILURE.
TPS “OutofRange” Fault
It is caused by the sensor reading going out of its allowable range. This fault can occur during the whole
range of movement of the throttle.
To diagnose this fully, it is recommended to operate the throttle through its full range. It is also recom-
mended to release the throttle quickly as this may also reveal a fault that is intermittent.
POSSIBLE CAUSES ACTION
Check if connector is disconnected from TPS
Reconnect.
Check if sensor is loose
Tighten sensor and reset
Closed Throttle
.
Inspect sensor for damage or corrosion Replace sensor and reset
Closed Throttle
.
Inspect wiring (voltage test) Repair.
Inspect wiring and sensor (resistance test) If bad wiring, repair.
If bad TPS, replace and reset
Closed Throttle
.
Test sensor operation (wear test)
Replace sensor and reset
Closed Throttle
.
TPS “Adaptation Failure” Fault
It is caused by the idle position moving out of an acceptable range.
Following failures can be effected by a TPS “Adaption Failure“:
– Idle speed is out of range.
– Engine stops, when throttle is released quickly.
– Engine runs inconsistent in low partload or low RPM.
POSSIBLE CAUSES ACTION
Sensor has been replaced and TPS closed position not
reset
