P0507
Idle speed is higher than the
target speed by 200 rpm
1. Engine is at idle.
2. Vehicle speed is equal to 0.
3. Engine coolant temperature is higher
than 60°C (140 ºF) .
4. Duration Longer Than 10 s.
3. Diagnostic Steps:
Note
Before carrying out this diagnosis step, observe the data list on scan tool and analyze the accuracy of the data, as
these will help with quick diagnosis.
Step 1
Check whether there are control system DTC codes other than DTC P0506 P0507.
(a)
Connect scan tool to the datalink connector.
(b)
Turn the ignition switch to "ON" position.
(c)
Press the scan tool power button.
(d)
Select the following menu items: Engine/Read DTC codes.
(e)
Read DTC codes.

Step 2
Check whether generator is working properly.
(a)
Use scan tool to observe whether the system voltage
parameters are normal.
Generator generating capacity normal?
No
Repair generator fault.
Yes
Step 3
Check intake air pressure sensor parameters.
(a)
Use scan tool to observe whether system intake pressure
transducer parameters are correct. Refer to "Data Stream
List".
Are intake air pressure sensor parameters normal?
No

Yes
Step 4
Check air-conditioning working condition.
(a)
Use scan tool to observe whether the Air-Conditioning
working status is consistent with the actual Air-Conditioning
working condition. Refer to the "Data Stream List".
When the air-conditioning is switched on and the pressure switch
voltage is greater than 0 V, does the idle speed increase by about
150 rpm?
Yes
No
Step 5
Check air intake system, exhaust system.
(a)
Check exhaust system for the existence of congestion, air
leakage.
(b)
Too much carbon residue in throttle.
Any of these malfunctions?
Yes
Repair the faulty parts.
No
Step 6
Check engine mechanical parts and accessory drive.
(a)
Shut down the engine and turn the ignition switch to "OFF".
(b)
Check whether engine accessory drive belt is slack.
(c)
Remove engine accessory belt, neutral gear. Rotate the
engine crankshaft check whether mechanical moving parts
catching.
(d)
Rotate engine accessory pulley and air-conditioning pump.
Check whether engine and other components catching.
Any of these malfunctions?
Yes
Repair the faulty parts.
No
Step 7
Check ECM power supply circuit.
(a)
Check whether ECM power supply circuit is normal.
(b)
Check whether ECM ground circuit is normal.
No
Repair the faulty parts.
Yes
Step 8
Replace ECM.
(a)
Replace ECM.

(b)
Carry out crankshaft position sensor self learn. Refer to the
"crankshaft position sensor to learn."

Step 9
Use scan tool to confirm whether the DTC code is stored again.
(a)
Connect scan tool to the datalink connector.
(b)
Turn the ignition switch to "ON" position.
(c)
Clear DTC code.
(d)
Start and run the engine at idle speed to warm up the engine
for at least 5 min.
(e)
Read control system DTC code again to confirm that the
system has no DTC code.
No
Intermittent Fault. Refer to
Yes
Step 10
Diagnostic completed.
5. Repair Instructions:
Replace throttle valve. Refer to "Throttle Replacement".

System Voltage Too High
ECM Power Supply Circuit consists of the following circuits:
–
Battery power passes through main fuse and EF04 to ECM harness connector EO35 terminal No.1.
–
When the ignition switch turned to "ON" position, battery power passes through the ignition switch wiring harness connector IP23
terminal No.6 to the ECU fuse 10, and finally to ECM harness connector EO35 terminal No. 3.
–
When ECM detects both ECM harness connector EO35 terminal No.3 and ECM connector EO35 terminal No.62 have battery
voltage, ECM grounds EO35 terminal No.62 through an internal circuit. Because EO35 terminal No.62 and main fuse terminal
No.1 are connected, the main relay pulls in.
–
When main relay pulls in, the battery power passes through main relay terminal No.3 to ECM harness connector EO35 terminals
No.6 and 22.
