Study guide General Description

Study guide The ESP system is the shorten word of Electronic Stability Program system. This system recognizes a critical driving condition by Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor. And then it stabilizes the Study guide and vehicle by a individual wheel braking and engine torque control through CAN communication. Among components of this system, the wheel speed sensor(WSS) is the essential component of the brake system. Study guide The ESP ECU(HECU, Hydraulic and Electronic Control Unit) uses the wheel speed sensor's signals to calculate a vehicle speed and also this Auto repair to determine whether a wheel lock occurs or not.

Auto repair DTC Description

Study guide of The HECU monitors the wheel speed sensor signal continuously and if the signal of a wheel speed sensor is omitted or too low, this DTC is set.

How to Chect Code P0880 TCM Power Signal Error Open/Short (GND)

How to Check Code P0880 TCM Power Signal Error Open/Short (GRD)

Component Location

 

Auto repair and Study guide General Description

The HIVEC Automatic Transmission supplies the power to the solenoid valves by way of a control relay. When the TCM sets the relay to ON, the relay operates and the battery power is supplied to all the solenoid valves. When the TCM sets the relay to OFF, all solenoid valve power is shut off and the transmission is held in the 3rd gear position. (Fail Safe Mode ) 

Auto repair and Study guide DTC Description

Study guide The TCM checks the A/T control relay signal by monitoring the contol signal. If, after the iginiton key is turned on, an unexpected voltage value, which is quite a bit lower than battery voltage is detected, the TCM sets this code. 

DTC Detecting Condition

How to inspect code P0507 Idle Control System RPM Higher than Expected

 

Auto repair and Study guide General Description

Auto repair and Study guide When the TP sensor’s signal indicates closed throttle position and the engine is idling, the ECM adjusts the idle speed control actuator so that the engine runs at the correct idling speed, regardless of coolant temperature, load and etc.Auto repair and Study guide When the additional load applied in the engine, the air flow through the idle speed control actuator is increased momentarily to raise the idling speed.

DTC Description( Auto repair and Study guide)

The ECM monitors engine speed deviation from the target idle engine speed when the vehicle is stopped and the throttle valve opening is stable. The ECM sets DTC P0507 if the difference to the target idle engine speed is higher than the predetermined threshold.

 

Possible Cause
● Monitor deviation between target idle speed and actual engine speed
● A stuck or binding throttle plate
● Maladjustment of the accelerator cable
● Contact resistance in connectors
● Faulty ICA valve

Detecting Condition

Enable Conditions
● Coolant temperature >73°C(163.4°F)
● Throttle angle: closed
● Vehicle speed = 0
● 10seconds after engine start.
● 10V< Battery voltage <16
● No relevant failure

Threshold Value
● Engine speed-Target idle speed > +200rpm (Engine speed too high)

Diagnostic Time
● 16 seconds

MIL On Condition
● 2 Driving Cycles
