1. General Description

Study Guide The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5V. If not, the sensor voltage is 0V. These CMPS signal is sent to the ECM and the ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

How to Check Code P0743 of Hyundai

Sonata FL 2009 G 2.4 DOHC Transmission Automatic Transaxle(A5GF1) P0743 Torque Converter Clutch Circuit Electrical

AUTO REPAIR AND Component Location

STUDY GUIDE AND General Description

The PCM/PCM/TCM controls the locking and unlocking of the Torque Converter Clutch ( or Damper Clutch ), to the input shaft of the transmission, by appling hydraulic pressure. The main purpose of T/C clutch control is to save fuel by decreasing the hydraulic load inside the T/C. The PCM/PCM/TCM outputs duty pulses to control the Damper Clutch Control Solenoid Valve( DCCSV ) and hydraulic pressure is applied to the DC according to the DCC duty ratio value. When the duty ratio is high, high pressure is applied and the Damper Clutch is locked. The normal operating range of the Damper Clutch Control duty ratio value is from 30%(unlocked) to 85%(locked).

STUDY GUIDE AND DTC Description

The PCM/PCM/TCM checks the Damper Clutch Control Signal by monitoring the feedback signal from the solenoid valve drive circuit. If an unexpected signal is monitored (for example, high voltage is detected when low voltage is expected, or low voltage is detected when high voltage is expected) the PCM/PCM/TCM judges that DCCSV circuit is malfunctioning and sets this code.

How to check code c1202 wheel speed sensor front LH invalid/no signal

This Auto repair and Study guide was trouble encounter from Hyundai Genesis regarding on ECS/ABS light indicator on some times while driving. this was the trouble code appeared from the GDS C1202 Wheel speed sensor but some of trouble can not immediately caught base on the trouble code given by the GDS this is only the basis so that every technician has pattern.

Auto repair and Study guide This trouble was solve and the cause was only from the tire. all tire defective oblong that’s why the sensor from wheel can not give good signal.

Component Location,Auto repair and Study guide

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 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
