Anyway about a month after I bought the car it stoped, local mechanic put it down to a voltage spike so new regulator was fitted with a new cam/crank angle sensor. Apon starting the car and taking it for a test run I was told the coil was faulty so it was replaced. The new coil lasted 5 minutes then that died so another one was fitted..I was not happy with the way the car ran as it had a intermitent miss a idol and felt like it ws surging..So plugs, leads, fuel filter were changed with no difference being found. I decided to take it to the local Holden dealer so they could use their Computer to sus out the problem and it came up with code 49. Making the car pulse injected not sequential.
The cam/crank angle sensor was replaced again but did not fix the problem, a new distributor was fitted this did not fix the problem either. So the ignition module was replaced new leads and plugs fitted again all earths and conections were checked, wiring from the distributor to the ignition module and the PCM was bypassed and new wires run..Still no joy..
New PCM and Memcal fitted, Holden technical boffins suggested a new engine wiring harness ($350) which was fitted and you guessed it still threw code 49 just running in the workshop. I disconected the wire to the tacho in hope it may have been the cause..nope!
In a last ditch effort we fitted a genuine holden VT coil and it ran like a dream in the workshop but as soon as you hit a bump it throws the code again.
Now as everything under the bonnet has been removed replaced checked several times do you think the problem may be under the dash on the drivers side between the BCM and the PCM?
Loose/bare wire or something?
Only reason I ask is when the brother inlaw bought the car he was given a service report from the dealer. OIl change, filter, machine brakes ect but it also had on the sheet the supply and fitting of a new steering column $785. The brother inlaw did not bother to ask why they fitted this before he bought the car and as it had only 45,000ks on the clock I have no idea why either...Also on top of the work sheet it had 5 codes and yep you guessed it one was code 49...So I think the car had this fault either when it was traded or after they fitted the steering column, either way I think they just cleared the codes and pushed it out the door as none of the codes would make the engine management light come on, and with code 49 it just reverts to pulse injection not sequential. So the average city driver would probably not even notice...
So anyone had this problem before?...... We have had a oscilloscope reading the cam sensor and it shows no problem but the hand held Holden computer comes up with cam angle sensor missing..
Is there anyway to reprogram the memcal to ignore code 49 or for it take no action so to speak?
Or should I, just to be certain that this is the dearest VT in Australia, replace the BCM and wiring under the dash or have it stuffed so it can be displayed in the Holden museum?
Its been in the worshop for 5 months now I want my car back..
Look forward to your replies...Cheers!
