Angry Mazda 323 BJ TPS Voltages

Does anyone know the correct output voltage for a TPS. I'd like to know this for both the FP 1.8 and FS 2.0 throttle bodies.

I need both the WOT (Wide Open Throttle) and Closed throttle Voltage range.

Thanks Guys and Gals

the sensors for both the FP and FS throttle bodies are the same, so the specs are the same

if you look for the often illegally distributed US Protege5 shop manual floating around on the internet, you will find that information in there

I've had a look through it but couldn't find it. Was hoping someone here might know. I'll keep looking.

I've always wanted to know if the TPS signal could be monitored (i.e. by a standalone ECU) without affecting the signal the stock ECU gets

Just put a meter on it

Ps did a google search and it looks like its just a 5v rail. So 0v is closed and 5v is fully open..

According to my TPS. Which could be buggered, my WOL max Voltage is about 4.45. Closed max is about 1 volt. When set like this the ECU has no idea about idle!!! I have it set currently at 0.45 for closed and the car is still not good. Power surges and the like. May be my TPS is stuffed.

Orion, I read somewhere that the Microtech will. Not sure how. But from what I read it will allow you to actually log the values from the TPS along with MAF value and Throttle %. Probably just teasing you, but I'm sure I read it somewhere!!!

This is from the service manual...
CTP 0.1—1.1
WOT 3.0—4.6

Of course this is the full range that you can get from the TPS. From fully clockwise to fully anticlockwise. According to Mazda anything in this range is acceptable.

According to me driving my car... NO!!!!!!

Are you still using the 1.8 FP-DE ECU to control the FS-DE????

Yes. I'd got it running pretty good. Not rich or lean. So I'd left it in. The TP sensor was the only thing not quite right. It's outputting about 0.47 volts closed at the moment. Every 0.01 makes a difference. But I really wanted it to be spot on. Hard info to get.

it might be easier to connect an OBD2 scan tool to the OBD2 port, it then can display any of the PID data, such as TPS voltage... adjust till you get it where you want!

perhaps in the future you should look into using the FS-ZE ECU and rebuilding your FS-DE into an FS-ZE... doable if you know how to build engines.... the FS-ZE ECU is nearly plug and play into the FP-DE's loom

This is going to be rather hard to do as the FP-DE ECU does not have OBD II. And neither does the FS-ZE.

Would the FS-ZE ECU happily run the FS Motor?? Or would it require the rebuild??

I forgot about that...
but the last sport20s FS-ZE (the 165ps version) *does* have the OBD II port... not true OBD II in the sense of the US government's eyes, but nonetheless it acts and works like OBD II

it does appear though that the earlier FS-ZE and the aussie/israeli FP-DE wiring does have the OBD II data lines connected to the ECU... since there is no real OBD II port under the dashboard, this data line only goes to the diagnostic connector under the bonnet.... under the KLN terminal... the pin which is across from the usual TEN terminal

I'm not sure if it is really an ISO 9141 data stream but it might be since the BJs with the OBD II port shares this data line between the two diagnostic ports

I think it's worth a shot hacking up some wires and connecting it to an OBD II scan tool... you'll want to connect it to pin 7 of the OBD 2 connector as that is the ISO 9141 data pin... earth you connect both pins 4 and 5 to any bare metal.... then for power, you connect pin 16 to a fused (10 amp or less) circuit

if it works, then you'll get all sorts of cool information from the ECU... you won't get OBD II codes, but you'll at least know what's going on!


the other alternative is looking for a Ford NGS tool with the appropriate mazda adapter and PCMCIA card for it... they're dinosaurs now and it'll take luck to find them! but it is the official tool that you use to connect it up to the under bonnet diagnostic port

it might run a little rich since the FS-DE is 9.7:1 compression and the FS-ze is 10.4:1

ok... new (re)discovery... after checking my 1999 Familia shop manual...
ALL FS-ZE ECUs *does* provide OBD II trouble codes... the early ones don't provide many codes... only 10 codes... the manual also says data monitors ARE supported in the FS-ZE...

so the KLN terminal does look more and more to me that it is an ISO 9141 data line....

so phil, it is in your interest to add an OBD II port under your dashboard then splice it off that data line leading to the engine bay... you can then get a scangauge or whatever if you want!!!


the manual does also state specifically that the FP-DE doesn't provide OBD II trouble codes nor data monitors... but that's JDM FP-DE

looking now at the 1998 European 323 BJ shop manual.... the 1998 FP-DE ECU did provide OBD II trouble code and data monitors through the engine bay's diagnostic connector, via the KLN terminal... so I think it's safe to assume that the BJ2 aussie/israeli FP-DE is also the same case since neither of these cars ever had OBD II ports under the dashboard (no BJ1 in Europe ever had OBD II ports)

so in other words, either hacking in an OBD II connector OR just simply just hacking in some wires between the engine bay diagnostic connector and an OBD II scan tool to get data off the ECU is a real possibility for the aussie FP-DE ECU!

That's all great. But can I replace my FP ECU with a ZE and run my FS motor better??

it may or may not run better... nobody has tried this, so I don't know

but there's one bloke who is wrecking his sp20... perhaps you should ask him for the engine loom, OBD II connector and wiring, and the ECU

he's in brisbane though

If he's asking the right price I don't mind paying for shipping. Although it would have to be an auto trans!!!

I know where there is a Manual FS-DE ECU and wiring loom.
Good luck finding a 4WD Manual Familia sport 20 that they are willing to sell ECU and loom off...

Just so you know Ed, I have the complete wiring harness off a SP20, as we were going to retro fit the climate control and now that my thoughts of the ZE ECU diagnosis connector wires being OBD II compatible I will now have to fit that side of the harness as well.
