Lets try this again: on a turbo engine there is no sub sensor. Either RTFM or slither under the car and look. I would've done that before asking a bunch of yahoos on the internet but hey, that's just me. Btw nobody "lives" in California, they only exist there. Actual living has long been...

Only Cali N/A cars have a sub sensor. USDM GTEs of any flavor (Cali and Federal) do not. That's a code 21 right there...

^ You keep doing this just to bug me right? Don't make me come down there :)

^ Reminds me of my trips up the Russian Woodpecker when I worked in the zone. Good times...

Kai: Knock, CPS and O2 are shielded on USDM cars. At least that's been my experience. It's also shown in the EWD. I'm puzzled as to why UK cars would be different. Ian: You're welcome. With the age of these car reaching a point where it appears mainly 12 year olds are working on them I'm...

Kia: It really ought to be shielded or at least twisted pairs. If you keep it away from the ignition secondary I suspect it'll be OK though. Ian: Yes. Generally speaking that's the case unless you're dealing with higher frequencies. For example with RF you would ground both ends.

What Kai said. I use shielded MIL-C-27500 for that kind of work. Overkill but I have plenty lying around. You could also run a new CPS cable directly to the ECU ala the knock sensor rewire. If you won't spring for 27500 something like twisted paired Belden #8723 will suffice. Run it along the...

Well, it can't use them if they're disconnected. Expect certain problems though...

Because you're confused about how the car works, that's why. Read what CyFi6 said again. It isn't about PSI. And regardless of the cause if code 34 is being set you *are* hitting fuel cut. That's what the code "does".

VTA should increase and reach appx 3.8 vdc @ WOT. Assuming your set up is mechanically correct wiring the Q45 equivalents of VCC and E2 backwards would result in decreasing voltage with increasing throttle plate angle.

He means the zero ohms you claimed to have measured in that circuit, caused by a faulty sensor heater or otherwise, would result in current flow far exceeding the fuse rating. Since he is correct you must be connecting or reading the meter wrong. However the heater circuit shouldn't measure...

You need to verify heater resistance at the ECU or check current anywhere along the circuit. That said there are other causes for code 21 depending on model year and where the car was meant to be sold but properly checking the heater circuit first would be the best place to start.

That logic is faulty and whomever provided you the basis for it is wrong.

"make sure its coming directly off the manifold"

^ Also causes aluminum to rust ;)

Sorry Jon, not that I know of. You could email one of those CARB guys in the press release and ask. I suspect any list will be further developed based on how current stations do between now and then. I wouldn't put it past BAR to play them off each other. Dirgle: you're welcome

There isn't any Jon. There isn't any at our place in Odessa either. A correction about the new program though. It doesn't take effect until mid 2013: http://www.arb.ca.gov/lispub/rss/displaypost.php?pno=4494

California has revamped it's Smog Check Program. Effective next year all vehicles model year 2000 and newer will have the inspection performed using OBD-II. This brings California in line with many other states in reducing the time and cost associated with testing these cars. However...

Those autoshop101 files are not supra specific and when reading them you have to filter what applies to the car and what doesn't. STP doesn't.
