Need help figuring out Mil Light code 2007 Nissan Sentra

[ahardb0dy]

Following the FSM for this 2007 Nissan Sentra I did what it said to read the codes using the MIL light in the dash, it keeps repeating this

 

10 slow blinks

5 fast blinks

10 fast blinks

7 fast blinks

 

than repeats the same pattern

 

I can't figure out how to interrupt this in the FSM, it is so complicated and doesn't explain very well

 

Anyone help me out??

 

Thanks

 

Just found something online that says a zero comes up as 10 flashes so my code should be - 0507 which lists as ISC system

 

need to look that up now, never heard of it,

 

if this sounds right please let me know, thanks again

A quick search of P0507 I found this

DTC P0507 ISC SYSTEM PFP:23781

Description EBS00C2G

NOTE:

If DTC P0507 is displayed with other DTC, first perform the trouble diagnosis for the other DTC.

The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let

into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is

varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects

the actual engine speed and sends a signal to the ECM.

The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value

memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.

The optimum value stored in the ECM is determined by taking into consideration various engine conditions,

such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan

operation, etc.).

On Board Diagnosis Logic EBS00C2H

DTC Confirmation Procedure EBS00C2J

NOTE:

l If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and

wait at least 10 seconds before conducting the next test.

l If the target idle speed is out of the specified value, perform Idle Air Volume Learning, EC-677 ,

before conducting DTC Confirmation Procedure. For the target idle speed, refer to the Service

Data and Specifications (SDS), EC-1301 .

TESTING CONDITION:

l Before performing the following procedure, confirm that battery voltage is more than 11V at idle.

l Always perform the test at a temperature above -10°C (14°F).

WITH CONSULT-II

1. Open engine hood.

2. Start engine and warm it up to normal operating temperature.

3. Turn ignition switch OFF and wait at least 10 seconds.

4. Turn ignition switch ON again and select DATA MONITOR

mode with CONSULT-II.

5. Start engine and run it for at least 1 minute at idle speed.

6. If 1st trip DTC is detected, go to EC-1036, "Diagnostic Procedure"

.

WITH GST

Follow the procedure WITH CONSULT-II above.

DTC No. Trouble diagnosis name DTC detecting condition Possible cause

P0507

0507

Idle speed control system

RPM higher than

expected

The idle speed is more than the target idle

speed by 200 rpm or more.

l Electric throttle control actuator

l Intake air leak

l PCV system

Might be a little helpful for at least being some input on what it is

thanks I looked it up and have been talking with Rob in PM's, damn car is too complicated, just to get the codes you need a stop watch and it took me like 5 tries before I got the sequence right !!!

 

I need a Consult tool !!!

Get a cheaper OBD2 reader, some of them are pretty nifty for not being a friggin Modus or something large!

iI can go to an autoparts store and have it scanned for free would love to have the consult tool so damn expensive even used ones

Yea, I sometimes forget I am lucky to have access to the things I can get my grimy hands on...
