ETC( Electronic Throttle Control) system consists of ETC DC motor, throttle

body, throttle position sensor and APS.
Both APS and TPS have 2 sensors such as APS1, APS2 and TPS1, TPS2
One of the biggest advantage using ETC system is fine controlling in idle. Throttle valve is directly controlled by DC motor without idle control devices such as ISA or step motor.

Delphi ETC has following features ;
- Fine idle control - Easy application for cruise control - Deicing function - Quick response - Reduced operating noise - DC motor operating voltage : 8~16.5V - TPS operating voltage : 4.5~5.5V

TPS characteristics
Two TPS outputs (TPS1 and TPS2) are used

for ETC system. TPS 1 starts from 0 to 5 voltage unlike TPS2 which starts form 5 to 0 voltage oppositely.

APS characteristics

APS1 is the main signal and APS2 is a back-up. APS2 output is the half of APS1. APS1 shows 0.7~0.8V but APS2 shows 0.29 ~ 0.46V at idle.

Failsafe
There are four main limphome functions in Delphi EMS
- Forced

idle - Limited performance - Power management - Engine shut down
Forced idle is followed when ECM doesn’t know about driver’s intension or A/D converter failure or ECM internal controller problem happens. When ECM goes to forced idle mode, any acceleration movement can not increase engine rpm. Rpm just sets to idle.
Regarding limited performance, when APS1 sensor has a failure APS2 becomes an alternative of APS1 and ETC system goes to limit performance condition. With this, increasing engine rpm is a little delayed even you depress to WOT. Engine rpm is limited about 2500.

Слайд 39

Failsafe
Unlike forced idle, power management is followed mainly from TPS failure.

Since now ECM doesn’t have any information from TPS, engine rpm and MAF value are used for feedback control. Under this power management condition, fuel cutting for specified cylinder and igntion timing retard happens resulting in rough idling and fluctuating. engine rpm is limited by 1800..
Engine shut down generally happens when you have TPS or DC motor problem with MAP&MAF failure. When this problem is detected, engine immediately shuts down.

Слайд 40

ETC System - Initializing
Every time when you make ignition on, ETC

goes to initializing for close (Point A). Generally it opens 15% of TPS value. In output voltage of TPS it becomes 1.1 ~ 1.2V. After ignition off then now ETC goes to open initializing. Throttle valve is forced to open from normal to 2.6v.(Point B)

MAP Sensor
MAP (Manifold Absolute Pressure) sensor is installed on the surge

tank. It detects the absolute pressure in surge tank and send it to ECM.
In case of WOT, some delay between the MAF sensor signal output and the real intake air flow (Transient Range), MAP sensor value replaces the MAF signal at those condition.
Also when MAF sensor failure is detected by ECM, MAP sensor is altered as an main sensor.

RPM Limit
Injector fuel cut at high rpm is not available at

idling (AT: P&N, MT: Neutral position). Because ETC controls throttle valve instead to limit engine speed less than 5000rpm under this condition. However injector fuel cut is available at driving range and engine speed limit is 6,800rpm.
