My mate has just got a UK TT Auto. Just test drove it and its lovely apart from.........

 

1. When you switch the ignition on the yellow light on the right hand side (middle light) comes on - then flashes 16 times.

It does this every time you put ignition on - whats this mean?

 

2. The boost guage, reads 0 on tickover, when you rev it it drops to about -5 then let go and it shoots straight back to 0.

When moving it goes upto about 9psi.

 

3. Its slow, I know the Auto will not be as quick as a manual(:D Stand back and await email assualts) but it is not very quick at all - it feels like theres no turbo kicking in. (and yes it is definately a TT)

 

Any ideas?

 

Cheers

The light flashing 16 times will be the "power" light and is telling you there a stored error code within the autobox ECU, the diagnostic he needs to do to find the error code is somewhere on AndyP's site http://www.300zx.org.uk or do a search on here.

 

The boost gauge - :eek: Doesnt sound too good, maybe a huge boost leak?? Should be very negative at idle. Although if its boosting ok, which 9si suggests :confused:, then it could be a simple problem withe the gauge, sender, or wiring. Either way, it should feel fast ;)

 

Pete

Cheers Pete, Its certainly not fast -

 

Ill have a quick squiz on that site. . . .

Just a thought - the slowness feeling could be due to the autobox error, is it kicking down properly? And does it sit in too high gear, that would obviously make it feel slow.

 

First port of call would be to do the diagnostic, and check the autobox ECU and engine ECU connectors are properly seated (mine wasnt some time ago and it stopped the car kicking down and changed up ridiculously early, thus feeling slow and sluggish). A simple plulling apart of the ECU loom connectors in the pass footwell sorted this out. And it costs nothing, so do this first ;)

Pete, cant find owt

I looked under ECU codes but 16 is not listed.

The 16 flashes only tells you there is an error, you have to perform the diagnostic procedure then read the flashes that happen then, I'll find the link ;)

Procedure:

 

1. Have the engine at normal operating temperature, in P with the overdrive switch on.

 

2. Start engine. The AT light (1.) should go out after 2 sec.

 

3. Turn the ignition off.

 

4. Move selector to drive D by using the Push Release button (2.). If not equipped, use the brake pedal

 

5. Set overdrive switch to OFF.

 

6. Wait 2 seconds and turn ignition switch ON.

 

7. Wait 2 seconds and move selector to 2.

 

8. Set overdrive switch to ON.

 

9. Move selector to 1.

 

10. Set overdrive switch to OFF.

 

11. Depress accelerator pedal fully and release it.

 

12. The codes will begin to flash. Theres one long flash that signifies the start of the sequence. Following should be 10 short flashes. Then it repeats.

 

 

Error Codes:

 

All 10 flashes the same = No error codes detected.

1st flash longer than others = Revolution sensor is shorted or disconnected.

2nd flash longer than others = Speed sensor circuit is shorted or disconnected.

3rd flash longer than others = Throttle sensor circuit is shorted or disconnected.

4th flash longer than others = Shift solenoid "A" circuit is shorted or disconnected

5th flash longer than others = Shift solenoid "B" circuit is shorted or disconnected

6th flash longer than others = Overrun clutch solenoid circuit is shorted or disconnected

7th flash longer than others = Lock-up solenoid circuit is shorted or disconnected

8th flash longer than others = Fluid temperature sensor is disconnected or A/T control unit power source circuit is damaged.

9th flash longer than others = Engine revolution signal circuit is shorted or disconnected

10th flash longer than others = Line pressure solenoid circuit is shorted or disconnected

All the same with no long start flash = Battery low, been disconnected, or control unit has just been reconnected.

Cheers Pete, will ring him and tell him

 

Thanks mate

No probs :) Probably quicker to fax him :D

I think he thinks Im winding him up with all the igniotion on ignition off move selector jump up and spin round etc.

 

Anyways hes off to do it now.

 

onyl thing he says is the AT light flashes 16 times when its meant to go off after 2 secs.

 

still Im waiting on a fone call

 

Thanks again pete.

3rd flash longer than others = Throttle sensor circuit is shorted or disconnected.

 

where do we start looking - ta.

found it - when he touches the cable on the TPS the idle drops etc

sounds like a break in the cable

Cool - thats a cheap fix, nice one :D Result.

 

A dodgy TPS connect really messes around with gearshifts and performance, dunno about the funny boost readings tho :confused: Cant see how they're related? Maybe there is a boost leak too?

yeah, I think were gonna have a look at boost this weekend

perhaps he should've put the extra money too it and bought yours Pete ;)

You still selling it?

Yeah dont remind me :cry: ;) I'm sure I'll be in another in a couple of years at most :cool: Hopefully mine again lol ;)
