3000GT error code 14
I've posted this question before but still haven't managed to solve
the problem. The engine warning light comes on intermittently on my
1991 3000GT SL. I did a fault diagnosis of the ECU as described in the
service manual and found malfunction code 14 for the throttle position
sensor.
I checked the throttle position sensor (TPS) and the idle position
switch with a VOM but both components seem to be working OK (as
described in service manual) . Not sure where to go from here. The
fault is intermittent and when it occurs the automatic shifting
becomes erratic. The fault ONLY occurs when engine is warm (after
about 1/2 hour of driving).
Someone previously suggested that it may be an earthing problem so I
renewed the earth straps from the battery to the chassis and engine.
This didn't help. Any further suggestions? Should I assume that it is
the TPS and replace it anyway? Maybe the intermittent nature of the
fault makes my checks of the TPS with a VOM invalid.

I have found that a good low conductivity ground strap from the Trans to the
frame solves many problems. Also a TPS can be intermitant and hard to
diagnose with a handheld meter.TG

Re: 3000GT error code 14
Thanks guys. I might wait until summer before pulling out the ECU to
check for faulty caps. AFA the TPS is concerned, maybe I should just
go ahead and replace it. I think a new one costs about £100. When you
say "ground strap from the Trans to the frame solves many problems",
you're talking about adding one aren't you? I don't think there is one
originally.

Yes, an additional strap. This especially helps auto trans cars. TG
