Code 22 wtf!!!!!

[NV-VN]

hey guys, before i start id like to thank you's for the online support its been great

i did a ecu check came up with code 22, baught a new sensor, then did ecu test came up with 12 so all good, i start the car, engine light comes back on (code 22) so i changed the plug.. start the car, engine light comes back on (code 22) as i did each step i reset the ecu

so whats the go now?
cheers

Check the wiring and connectors that go from the TPS - Throttle Position Sensor, through to the ECU.Unplug and then plug back in the wiring connectors a few times to make sure theres good contact in the connectors.Also check the wiring connectors at the ECU itself for corroded pins in the connectors.Also the TPS could be faulty.Ive also seen new cheap brand sensors cause problems like this,its best to buy genuine holden sensors instead of cheaper ones.

im going to change ecu and see what happens. because the plug and sensor are getting contact. its shitting me now just spent 40 bux and isnt the sensor

[db_notso]

clear code again!~
take battery negative off for ten minutes
remove sensor and plug it in (loose)
reconnect battery
start car and see if codes still sets (dont touch accelorator)
if it does NOT RESET the code: tps installed incorrectly
if it does and sensor okay.......

just to double check this is in a vn v6 v8 etc... (sounds stupid but the diagnosis is different and dont want to lead you down the garden path man)

yep vn 6. theres no way of installing it incorrectly. its 2 screws with a washer and spring inbetween the throttle metal thingy and the sensor. or am i missing something?

The gregorys workshop manual for the VP V6 says-To install the TPS-With the throttle valve in the fully closed position,install the throttle position sensor onto the throttle shaft at a position 30 degrees clockwise past the throttle position sensor retaining screw holes in the throttle body.Align the holes in the throttle position sensor with those in the throttle body,install the screws and tighten securely.
Id say the VN would be the same.

[anfo]

possibly a faulty new sensor?

[NV-VN]

hey brett i tryed putting it 30 degrees like you said, and when i started it car was revving very high(3000rpm) so mabey its different in the vn

Yeah,maybe it is different then,Ive also got a VN-VS V6 and V8 haynes manual it says:
Disconnect the electrical connector from the TPS,remove the torx screws from the TPS and remove the TPS from the throttle body.
When refitting the TPS,be sure to align the socket locating tangs on the TPS with the throttle body.Refitting is the reversal of the removal proceedure.
Oddly enough,the instructions in it for the V8 says to turn it 30 degrees to locate it,then turn it back and screw it up though.
The haynes manuals are pretty bodgey though compared to gregorys manauls.Even my VS V6 gregorys says to turn it 30 degrees etc,which I have done lots of times to put it back on ,and have had no problems.So I just dont know what the go is with the VN one,maybe someone here has a VN gregorys that says how to do it.

sorry for the noob question brett.. but from which angle am i looking at the throttle body to turn it 30 degrees?
i had the sensor on the top with the connection plug facing me? and to make sure, all thats in between is a washer and spring?

[Brett_jjj]

Its sort of hard to explain.You just put it together like you normally would, but you dont line up the screw holes when you push it on,you go a bit past them so they are just out of alignment with eachother(30 degrees),then once its pushed on,you turn the TPS back a bit, and then line up the screw holes and put the screws in.Also theres a small square adaptor block on the VS ones,it looks like the VP one is a bit different.The pic in the VP manual doesnt show anything between the TPS and the throttle body.The haynes manual says theres two washers and a spring between the TPS and the throttle body,but doesnt show them in the picture,pfff.Mate I hope that helps you a bit.

22 Throttle pos sensor below .2 volt for 2 seconds while engine running
thats what i found... so if voltage too low could be loose connection in that circuit
you would need to check if the "female" pins on the connector are opened up too wide
or if the harness leading too that connector is pinched somewhere (around top lh motor?)
that is if having sensor loose still sets code as above

Also theres a small square adaptor block on the VS ones,it looks like the VP one is a bit different.The pic in the VP manual doesnt show anything between the TPS and the throttle body

I've found VN S1 throttle have no small adapter block while the later onwards VN S2 have one.

[db_notso]

no fix????? do u have solution ???????

[delcowizzid]

the spring and washer should have a plastic adaptor on the outside of them if its fallen off you will get the tps code too

[NV-VN]

ohh i havent heard that one before.. if this true for all vn tps? because that means i have to go wreckers (no licence) i called repco and autobarn and they dont know what im talking about with the plastic adaptor.

[delcowizzid]

some TB's have then some the tps runs directly on the shaft as its a different size

[NV-VN]

hmm sounds about right because the leaver of the throttle that sticks in the sensor, seems to be thinner than than the little lips inside the sensor to turn it. if you get what i mean, i might have to go wreckers and check a few different ones see if one has it

[db_notso]

yes then your missing the cap that sits on the shaft UNDER the tps
explains why code sets when rev it....

[NV-VN]

FIXED . thanks guys for all the help it was the cap over the shaft. when i went wreckers 4/5 vns didnt have the cover, but all i needed was the one =D im a happy man
