code 51 , 24 low idle

[silvergsx623]

I was driving and the engine shut off when i mashed in the clutch when pulling up at a stop sign. I got it to start back up, but it wouldn't idle on its own. I had to give it 4% throttle to keep it ideling. I pulled over and checked stuff, adjusted settings on my afc and i got it to idle at 500 rpms. It can not catch its self if i rev it, the engine will stall. It is not running lean or rich by my wideband. its 14.6 ish at idle.

It threw code 24 and 51

So im guessing this could be the TPS sensor?

Any ideas?

Thanks!!!

I have a 2jzge na-t if it matters

after letting the car sit for about 2 hours with the battery disconnected...
It will idle by its self now, but when ever i touch the throttle, it will bog and almost die. It will recover back to idle by its self now.

My wideband is showing very lean now, 19.6ish at idle... :1zhelp:

now showing code 51 only

My safc 2 is showing a .724 - .725 volt on the tps.
Is that normal?

I reset the codes and it threw the 51 again.

On my AFC i am seeing voltage from the tps. roughly .7 at idle.
I am seeing nothing from AFL on the afc.

When ever i touch the gas, my wideband shows the motor going lean, and it almost dies.

Any thought , ideas, comments?

Thanks guys:cry:

check the connections and codes :

51 -
SWITCH SIGNALS
IDL (tps) CONTACTS OFF, NEUTRAL START SWITCH OFF, A/C SWITCH "ON" SIGNAL TO ECU WITH DIAGNOSTIC CHECK CONNECTOR SHORTED

--A/C SWITCH/CIRCUIT
--A/C AMPLIFIER
--TPS/CIRCUIT
--NEUTRAL START SWITCH/CIRCUIT
--ECU

24 = INTAKE AIR TEMPERATURE SENSOR SIGNAL--OPEN OR SHORT IN INTAKE AIR TEMP. SIGNAL
--INTAKE AIR TEMPERATURE CIRCUIT
--INTAKE AIR TEMPERATURE SENSOR
--ECU

Its not throwing the 24 any longer.

Still getting the 51 though.

What type of voltage should i see from the tps at idle? (voltage display on my apexi safc 2)

thanks
