never a walk in the park with a vehicle that has 245.000kms

Fuel Trims Are Adding Fuel As The System Is Running Lean
Conduct Road Test And Found That The Fuel Trims Are Causing The Check Engine Light To Come On


The Fuel Trims Are Suspect That The Systems Has Air Leaks Of Air Flow Meter Fault It Also Shows That There Is A Fuel Delivery Problem
Disconnect Fuel Lines And Connect A Fuel Pressure Gauge

After Some Time Running The Vehicle The Fuel Trims Have Come Down To +10% To +15%
Getting Closer When Accelerating The Engine It Felt Sluggish,
So An Air Mass Meter Was Purchased And Installed (after Market ) It Was Found That The Fuel Trims Where In Fact Worse, So The After Market Crap Unit Was Sent Back And A Genuine Unit Was Installed!!
At Last The Fuel Trims And Acceleration Was Back Fuel Trims Average At +3% Mark


Drove The Vehicle Home 35 Min Drive And The Vehicle Felt Sluggish Again, Tested The Fuel Trims To See If Any Changes And Found That Fuel Trims Had Gone Worse Than Ever Back To +44% A Fuel Trims and Air Flow Meter Test Was Done Again And Only The Fuel Delivery Side Was Bad
Remove The Seat And Gained Access To The Fuel Pump And Found The Pre Filter Had A Layer Of Mud And Pet Hair,cleaned The Pre filter And Washed The Fuel Pump Bowl Refitted To Vehicle And Test Driven Again For The 35 Mins And Found The Vehicle Is Now Free From Errors, And All Power Is Restored At 200 hp

Previous Repairs, and the short story

The vehicle was delivered to us after talks about the original issue with the vehicle, which was poor performance and fuel trims high +45.

During the Conversation about the vehicle it was decided that a new air flow meter be installed and the vehicle test driven to confirm the fuel trims are coming back into line (+ or – 6%)
The vehicle was fitted with a new aftermarket air flow meter and fuel trims checked on the test drive.

Holden Commodore VE – 04/2008 LEO V6 Engine – Random stalling

the 2 fault codes present every time after we scanned this vehicle was

Engine ECU
p0850 – Park/neutral signal Circuit Incorrect.
Audio System
(fixed this one too)
B101d-3c – Ecu, Hardware Performance fault.

Time to get out the workshop manual and start testing the circuits.
we did find a few things online that did not mean much at the time but might help down the track


Diagnostic Trouble Code Results for B101D for the Holden Commodore (VE)
EedHolden 
Diagnostic Trouble Code: B101D

Vehicle Make: Holden

Diagnostic Code Entered By: ZerOne
Diagnostic Code Entered On: Wed Oct 06, 2010 11:00 pm
Please Note: The DTC Information provided has been randomly generated.
To view the correct Diagnostic Code Information, Please Login, or Register. Diagnostic Trouble Code Description: Throttle position sensor (TP1) out of self-test range.

Possible Module Faults
Accelerator pressed during self-test when not required. (Possible cause, driver pressing throttle at or just after key-on.)
this does not state if this fault is in the radio or the Engine ECU

none of the above was the fault,

after seeing the vehicle week after week, when the vehicle was playing up the throttle was removed and it was found that the throttle blade was sticking, removed and cleaned out the pivots and flushed with carby cleaner,

refitted to vehicle and it has not played up since,
so dont worry about the fault codes they have nothing to do with it, just a dirty throttle in the pivot bushes, so removed the throttle body and clean properly and you will find it works better.

We have started to collaborate live data sets and possible control unit resets to vehicles as there is just too many variants in vehicles these days, and the live data at idle varies between models,

Ford Falcon body control modules FG1 & FG2

A vehicle came in this week and BCM replaced with new unit supplied from ford, a local locksmith had carried out key programming and parameter reset, got the vehicle started (cool)

Post starting the vehicle, the vehicle locks did not work correctly and the BCM configuration thought it was a 4wd and a wagon ( no way)
1. the door ajar switch is open when door closed and closed when door open.
so the BCM is wired differently or opposite in the FG2 Compared with the FG1
