Throttle Position Sensor (Tps); The Engine Coolant Temperature Sensor - Kia Sorento 2003 Technical Highlights

Section 4 • Fuel and Emissions—Sensors
The Throttle Position Sensor (TPS) consists of
Throttle
a potentiometer together with an idle switch, which
Position
is installed on the throttle body assembly. TPS in-
Sensor (TPS)
formation is shared with the TCM via the Controller
Area Network (CAN). In addition, a Pulse-Width
Modulated (PWM) version of the TPS signal is
transmitted by the ECM to the torque-on-demand
transfer case control unit (TCCM).
TPS Values
• 0.3-0.9V @ idle
• 4.0-4.6V @ WOT
• The Idle Switch is monitored separately from the
TPS signal and has its own DTC (P0510)
• TPS percentage, voltage, and idle switch status
can be viewed in Hi-Scan Current Data

The Engine Coolant Temperature Sensor

Engine
(ECT) is installed in the water outlet fitting and sup-
Coolant
plies the ECM with coolant temperature information
Temperature
in addition to controlling the temperature gauge on
Sensor (ECT)
the instrument cluster. The ECT is fitted with gold-
plated terminals. The ECT is a negative temperature
co-efficient thermistor.
ECT Output Values
• 3.2-3.8V @ 32
• 2.3-2.8V @ 68
• 1.5-2.1V @ 104
• 0.4-0.8V @ 178
• ECT (temperature) is viewable in Hi-Scan
