my car is throwing a tps code.....******* str tb....anyway why would it run really rich? My car idles like **** and keeps dieing.....my car smells like a ******* domestic

 

because teh ecu thinks the throttle plate is open, so it adds fuel, and since its not actually open, your not getting enough air to mix with all the extra gas, so it runs rich.
Are you sure you did not mix up the connectors for the TPS and the MAP? This will cause this too.

 

um i dont think thats possible...the clips are different

 

no there not!
go check for yourself!

 

i already have

 

then you found out that they are in fact the same connector if you know which ones they are.
I have seen this be the case at least 10 different times.
the TPS will have a green/blk, a yel/blu, and red/blk wires.
The map will have a yel/red, red/grn, and grn/wht wires.

 

hey mo, how can i fix this problem, i got that same code and my ***** running really rich too. what can i do to fix this problem, and my car idles rough also, the shop i went to told me to change O2 sensors to fix rough idle and so i did, but still idles a lil rough (never used to). plus check engine light comes on but the shop said the ecu has to reset itself, is this true? plz reply...

 

okay im going to double check...but im pretty shure i didnt.....i just got my tb back from str and i couldnt figure how to calibrate it and check it cause of my aftermarket wiring harness couldnt find the blue and white wire to check for varying voltages

 

EKguy, what code do you have?
have you checked the connectors to make sure they are not backwards?

 

ekhybrid, what color are the wires on your tps?

 

yeah just checked i didnt mix them up.

 

one is white/blue
one is red black
and one is green

 

what year cars?

 

i have a 98 civic cx hb, and its run fine before, no rough idling, have had car for about a year and some and its run fine before, no probs, but i did change prim O2 sensor, whats a map sensor (sorry newbie here), where is it located and how do i check it. valve clearance, how to fix that? and ive put same gas for a yr and never any problems

99civic
its got a 94 jdm b18c converted to obd 1...i didnt do the wiring though

 

probably a P0172... (to rich code also a code 45)
Heres what can cause it...
MAP sensor
Valve Clearance to tight
bad gas
or a bad primary O2 sensor

This is all of course if your wiring is fine which it probably is unless you or anybody else have not messed with it.

 

which ECU are you using?
and has it run right before with this setup?

 

yes its ran fine had the current set up for about 5 months no probs....with this of course...had countless other problems.....endless money pit

 

check your TP singal input it should be .49 volts with throttle close. also check referrence voltage spec. is 4.9-5.0 volts and ground should be less than .4 volts.

But make sure that the TP cali. to .49 key on engine of(KOEO).

 

yeah but my wiring is all crazy with my motor swap i cant find the blue/white wire to check for various voltage...you didnt read my previous post?

 

Yes. So did this happeno after you replaced the tb with a str unit?

 

the signal input wire will be the wire in the middle of the 3 on the TPS connector.

obviously its not going to be green or the blue/white the one ive been talking about

 

not understanding the last comment...

 

does the tps sensor have anything to do with vtec engagement?..sorry to change the subject just a quick question
