Lambda Engine © HMC & KMC reserves all rights of disposal such as copying and passing on to third parties. This book should be used for the training purpose ETC System

Lambda Engine © HMC & KMC reserves all rights of disposal such as copying and passing on to third parties. This book should be used for the training purpose ETC System-Main Components Two TPS are used in ETC system. TPS1 and TPS2. TPS 1 starts from 0 to 5 voltage unlike TPS2 which starts form 5 to 0 voltage oppositely. At idle condition it shows around 0.6 voltage in TPS1. APS1 is the main sensor and APS2 is for alternative. APS2 value has the half value of APS1. When one APS sensor problem is detected, another APS sensor is replaced as a limphome function. At idle condition without any throttle pedal movement, APS1 shows 0.7~0.8V but APS2 shows 0.29 ~ 0.46V. Rationality checking is also done by ECM. When there is big difference such as more than 1 voltage, it goes to limphome function too. Relevant DTC : APS(P2123, P2122, P2126, P2127, P2138), TPS(P0125, P0122, P0223, P0222, P2135), System(P0641, P0651, P2173, P0638, P2104, P2105, P2106, P1295)

Lambda Engine © HMC & KMC reserves all rights of disposal such as copying and passing on to third parties. This book should be used for the training purpose There are four main limphome functions in Delphi EMS - Forced idle - Limited performance - Power management - Engine shut down Forced idle is followed when ECM doesnt know about drivers 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. Unlike forced idle power management is followed mainly from TPS failure. Since now ECM doesnt 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 happens resulting in rough idling and fluctuating. Engine rpm is limited by Engine shut down generally happens when you have DC motor problem. When this problem is detected, engine immediately shuts down. ETC System – Limphome

Lambda Engine © HMC & KMC reserves all rights of disposal such as copying and passing on to third parties. This book should be used for the training purpose 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 ~ 1.2. After ignition off then now ETC goes to open initializing. Throttle valve is forced to open from normal to 2.6v.(Point B) ETC System – Initializing

This book should be used for the training purpose ETC System – Forced Idle Look at range A to B. Even APS1 signal reaches 4.29V, engine rpm still show 750. It means it goes to forced idle condition. With this condition, only DC motor – side is energized and make just proper air passage is open. Motor + side becomes ground.

Lambda Engine © HMC & KMC reserves all rights of disposal such as copying and passing on to third parties. This book should be used for the training purpose 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 When you depress the brake pedal engine rpm immediately drops to idle. ETC System – Limited Perforcemance
