How to check fuel/system pressure too low

2006  D 2.9 TCI-J3  Engine  Engine Control  P0087 Fuel Rail/System Pressure - Too Low

Auto repair and Study guide Component Location

 

General Description

Auto repair nad Study guide At Commom rail diesel engine, rail pressure regulator is controlled based on rail pressure sensor signal in order to maintain optimum rail pressure according to current engine rpm and load.

however when a trouble, which leads rail pressure to out of target value intended by ECM, occurs due to mechanical or electronical reason, ECM shuts engine down and sets DTC by limiting fuel (stops injector operation) in order to prevent engine from being controlled abnormally. "rail pressure monitoring error" is the DTC which diagnose 1).supplying state of low pressure fuel and 2).mechanical operating conditions of high pressure pump and rail pressure regulator indirectly based on rail pressure sensor output voltage and rail pressure sensor duty. thus, repair relavant to this DTC requires mechanics the total understand of fuel system

DTC Description

When rail pressure is lower than target rail pressure, ECM tried to raise rail pressure as decreasing fuel press. regulator current(increasing fuel supplied to common rail). If meeting real fuel pressure to target pressure is failed to achieve, P0087 is set.

When this code is set, check possible causes which decrease fuel pressure such as 1)close stuck of fuel press. regulator, 2)lowered efficiency of high press. pump, 3)fuel leakage, 4)excessive returning quantity of fuel from injector, 5)clogged low press. pump filter.

How to check CKP(Crankshaft Position Sensor) of Hyundai Terracan

How to check the CKP of Hyundai Terracan.

2006  D 2.9 TCI-J3  Engine  Engine Control  P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

 

Auto repiar and Study Guide Component Location

 

Auto repair and Study guide General Description

※ Cam shaft position sensor

Auto repair and Study guide, Cam Shaft Position Sensor(CMPS) is hall sensor type. Sensing the teeth attatch at the end of exhaust cam shaft, CMPS detects rotation of Cam shaft (1 signal per 1 lotation)

As Cam shaft rotates once while Crank shaft does twice, CMPS referrence point generates once while CKPS do twice.Study guide

As this signal inputted to ECM, it distinguishes crank angle and the cylinder which requires fuel injection in order to determine injection sequence and duration.Study guide

※ Crank shaft position sensor

Auto repair Crank Shaft Position Sensor(CKPS) is magnetic inductive type. Mounted on transaxle hausing, it senses tone wheel position of fly wheel.

As tone wheel is devided with 58 teeth and 2 missing teeth (referrence point), 1 tooth corresponds to 6 degree.

CKPS which calculates RPM and crank angle is important to determine fuel injection quantity and injection timing with APS. Crank shaft position is closely related to engine starting,Study guide.

Auto repair and Study guide DTC Description

P0016 is set when timing system error occurs. This code is due to 1) incorrect correlation between CKP reference point and CMP reference point, 2) The failure of reference point synchronization because of abnormal output signal from CKP or CMP 

DTC Detecting Condition

Detecting Contion
● Failure occurs at cranking : fuel injection stops(engine ON is impossible)
● Failure occurs at engine running : using cylinder data before failure happens. Engine running is possible only untill engine OFF.
Check lamp

Auto repair and Study guide Possible Cause
● CKPS and CMPS reference points not synchronized properly
● Poor timing belt arrangement
● CKPS circuit
● CKPS component
● CMPS circuit
● CMPS component
● Too wide air gap

 

Auto repair and Study guide Signal Waveform

※ CMPS Signal Waveform Analysis

1.ECM recognizes HIGH signal as LOW signal when CMPS signal drops below 2.0V and LOW signal as HIGH signal when CMPS signal rises above 3.8V.Study guide.

2.V0 - the Minimum voltage of LOW signal does not drop below 0.0V due to the hall sensor inside resistance. When the Minimum voltage of LOW signal is above 0.6V during signal waveform inspection, check excessive resistance inside of CMPS component or in ground circuit.Study guide.

※ CKPS Signal Waveform Analysis

1.The output voltage of CKPS signal varies according to rpm(the speed of tone wheel passing by sensor)

(low voltage is inducted for low speed and high voltage is inducted for high speed.)

2.Auto repair and Study guide, CKPS should detect from low rpm at cranking to above 5000rpm. If minimum detecting voltage is set low for the ease of signal detection at low rpm, 1) the abnormal signal at high rpm from which high voltage generates or 2) electrical NOise through circuit can be recognized as Crank signal. Thus minimum detecting voltages at low rpm and high rpm are set differently.

3Auto repair .ECM convert analog signal like the waveform illustrated above into digital signal with A/D converter.The voltage above minimum detecting voltage of crank signal and "-"voltage below 0.0V is meaningless at converting process. RPM is detected as Hz.(signal detecting period)

 

Study guide Monitor Scantool Data

1.Connect Scantool to Data Link Connector (DLC).

2.Warm engine up to normal operating temperature.

3.Turn "OFF" electrical devices and A/C.

4.Monitor "ENGINE SPEED" parameter on the Scantool.

A.Specification : 800±50RPM at idle

How does starting system of Hyundai Coupe works

 

Engine Electrical System

Auto repair and Study guide Description

The starting system Study guide includes the battery, starter, solenoid switch, ignition switch, inhibitor switch (A/T), ignition lock switch, connection wires and the battery cable in Auto repair.

When the ignition key is turned to the start position, current flows and energizes the starter motor's solenoid coil.

The solenoid plunger and clutch shift lever are activated, and the clutch pinion engages the ring gear.

The contacts close and the starter motor cranks. In order to prevent damage caused by excessive rotation of the starter armature when the engine starts, the clutch pinion gear overruns.Auto repair.

Troubleshooting Starter Circuit

 

This Study guide The battery must be in good condition and fully charged.

1.Disconnect the fuel pump connector.as Study guide.

2.With the shift lever in N or P (A/T) or clutch pedal pressed (M/T), turn the ignition switch to "START"

If the starter normally cranks the engine, starting system is OK. If the starter will not crank the engine at all, go to next step.

If it won't disengage from the ring gear when you release key, check for the following until you find the cause.

A.Solenoid plunger and switch malfunction.

B.Dirty pinion gear or damaged overrunning clutch.

3.Auto repair and Study guide ,Check the battery condition. Check electrical connections at the battery, battery negative cable connected to the body, engine ground cables, and the starter for looseness and corrosion. Then try starting the engine again.

If the starter cranks normally the engine, repairing the loose connection repaired the problem. The starting system is now OK.

If the starter still does not crank the engine, go to next step.

4.Disconnect the connector from the S-terminal of solenoid. Connect a jumper wire from the B-terminal of solenoid to the S-terminal of solenoid.

If the starter cranks the engine, go to next step.

If the starter still does not crank the engine, remove the starter, and repair or replace as necessary.

5.Check the following items in the order listed until you find the open circuit.

A.Check the wire and connectors between the driver's under-dash fuse/relay box and the ignition switch, and between the driver's under-dash fuse/relay box and the starter.

B.Check the ignition switch (Refer to ignition system in BE Group).

C.Check the transaxle range switch connector or ignition lock switch connector.

D.Inspect the starter relay.

Auto repair Starter Solenoid Test

1.Disconnect the field coil wire from the M-terminal of solenoid switch.

2.This Study guide ,Connect the battery as shown. If the starter pinion pops out, it is working properly. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.

3.Disconnect the battery from the M terminal.

If the pinion does not retract, the hold-in coil is working properly. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.

4.Disconnect the battery also from the body. If the pinion retracts immediately, it is working properly. To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.

Free Running Test

1.Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12-volt battery

to starter motor as follows.

2.Connect a test ammeter (100-ampere scale) and carbon pile rheostats as shown in the illustration.

3.Connect a voltmeter (15-volt scale) across starter motor.

4.Rotate carbon pile to the off position, Auto repair.

5.Connect the battery cable from battery's negative post to the starter motor body.

6.Adjust until battery voltage shown on the voltmeter reads 11.5volts as Study guide.

7.As Auto repair and Study guide , Confirm that the maximum amperage is within the …….
