Not related to your noise but i had one once that kept ticking from the drivers side even after new lifters and chains, pulled heads and found a small piece of oil filter element stuck in one of the oil ports, as pressure built up with rpm it would move slightly and restrict flow, let it idle...

Hi everyone, Ive searched the forums and found a lot of mention of the files I am looking for but no information of where to find them. I am searching for the map update files for the VE IQ system. My car still has the original maps from its manufacture in 2011 and my street is not even on...

They have to be a long way out to throw a code normal operating range is like -40 to 200 (cant remember exactly for the 304 but around there). An open circuit will also default to full cold temp usually. A TPS has a small range of .5 to 4.5v and is far more sensitive to small differances from spec

Well he has already tried a coolant temp sensor so its a non issue now. But a coolant temp sensor can still be within the ecus acceptable temperature range but the incorrect temperature, so no codes will log for it. The other way is to check resistance of sensor at different temps and compare to...

If you read my earlier comment I already explained the 2 sensors. And also the single wire sensor does not feedback to the ecu, therefore checking the live data with a scan tool will give you the information required from the correct coolant temp sensor. So not misleading at all.

Yeah if engine thinks it is at -40° it will over fuel like hell. If it still has a circuit it may not throw a code. Need to check the live data and see what the temp reading is at to confirm. Checking injectors is also never a bad idea, had quite a few in recent years with stuck injectors.

Coolant temp sensor is a common fault of 304s, there is 2 in the front on the engine, the single wire controls the temp guage, the 2 wire is coolant temp to ecu. If they die the engine overfuels as it thinks it is way to cold. If you have a scan tool that can connect to the car your should be...

https://www.injectronics.com.au/register-a-repair/details/abs-module/220 They list it under the same part no for a reman unit so you probably can Pretty sure i have done that same swap in the past

Need to check it when engine is cold and the fault occurs

Check what the coolant temp sensor is reading in live data

Dont fire the parts cannon off its an expensive game that. Check what sort of g/s the air flow meter is registering, maybe give it a clean if it has a k&n filter as the oil can contaminate it Check advance/retard of each cam in the scanner see if anything stands out, I know i can see that...

Can still be stretched and out of time without a rattle. Have you checked the misfire counter in live data on the autel to see if any specific cylinders are dropping out?

Hahaha no beginner I know has an MDI 2 In regards to checking the chains we circle back to checking the oil pressure, the 3 chains all use an oil fed tensioner, if you have low oil pressure the chains will not tension properly, will make noise and can be damaged

Thats just an updated calibration, allows a bit more tolerance in the chain wear before it triggers a fault. You have access to TLC tho so your way ahead of a lot of people. Are you using tech2win for diagnostics?

Yeah hopefully not, id be looking at oil pressure,if your pressure is ok replace the sensor, then check timing related stuff, they can do some really funny things when the vct gears or oil control valves for the gears go, but it is more likely a failed chain than those 2. All of the above I have...

Never mess around with oil pressure, always check actual pressure before replacing the sensor. Not to be rude, but all the other stuff you have posted about with exhaust, o2s, inlet etc should of been left alone until you looked at the cause of the oil pressure code.

Did you check oil pressure and replace the sensor? The video you have of the engine running sounds like it has a stuck vct actuator causing the cam timing to be way off. I have this issue quite a bit on rattletecs that have not been serviced well

I wouldnt just go and buy 02 sensors on a whim. If you are somewhat mechanical I would remove the cats and do a visual inspection before doing anything else. Alternativly use and obd reader and see what the voltage readings for the 02 sensors are first.

I would be checking what your 02 sensors are reading, you could have a collapsed cat converter

Did you have any luck finding your issue yet?

I have seen the ecus fail due to temp, normally tip some cold water on the metal side and it will start again. Requires replacement ecu. Is the ecu they have fitted new or 2nd hand? Did they specify what issues they had when programming it?

I have the GM service info that covers up to 2009 Holden on a virtual machine I can share with anyone that wants it

Did you use the crewman ecu or the sv8 ecu? If you fitted the crewman ecu to the sv8 it will not go as it will have a security match error.

Check your brakefluid level

Looking at all the voltage low codes, i would suspect damged wiring. Best advices would be to go on acdelcotds and get some wiring diagrams, check if those componants share a power or ground circuit and work backwards from there. Being the fault happened when cornering and then after being moved...

I have had similar issues on the direct injection 3.6 engines when the purge valve is faulty. Under load and rpm the fuel trims would be fine. When left idling for a long period the long term fuel trims would climb to 25%. The past vehicle actually started out with a misfire after filling the...

Yeah as I said earlier this is all speculation without actual codes and data. Can you post a picture of your engine bay and also a close up of the headers. I want to see if the maf is still in there and if it still has standard manifolds/headers mated up to an xforce rear system

If the codes have been turned off correctly in the tune side of things then you should not get an engine light for those codes ever. They would still appear as a permanant code with something like hptuners, but your run of the mill obd2 scanner, and even most scanners a workshop uses wont pull...

What you are describing is exactly what happens when the abs unit fails. Easiest way to diagnose is to wait until it does it again and just unplug the abs module, if tech2 communicates and all lights but the abs one go out it is the abs module

If the mechanic that read them knows what they are looking at with the 02 voltages (alot of people do not know how to accurately understand 02 voltages) and your previous sensor failed due to damage it is possible the cat converter has failed, it could be blocking the exhaust causing your...

What is the actual code number? There is multiple codes that relate to Bank 1 Sensor 2. Posible causes can include vaccum leak, bad injectors, failing cat converter, bad wiring to sensor, failing ecu etc. First step to accuratley diagnose is to get an actual code number and description...

Unplug Abs pump and retry scanning with tech2. Have seen quite a few where the abs module fails and shuts down the canbus network, also causes a christmas tree on the dash

Check for air leaks, normally caused by split pipe after maf sensor, also purge valve leaking is common

If you are refitting make sure you do a spin and push on the converter to ensure it is right back, can damage the converter and pump in the trans if you dont

Pull a sensor out and check the part number on the side of it

Try matt at Fermec

It will seperate from the trans as long as you have bellhousing and coverter bolts out. Make sure to push the converter back towards trans once it is unbolted.

Couple of pictures if you guys are unsure, programming a new iq unit to my car today using the clone device i purchased

Contact Matt at Fermec. Can be turned off via obd plug with the right gear. There is a speed limiter fault that I had to turn off in the tune side of things as well

If you have any patched or cracked software on your system when you install techline connect it removes it and installs the latest version of the software
