I don't see a connection with the abs...separate problem I would expect.

Go after the tps, sounds like code po121. Mitchell gives a procedure to troubleshoot:

The TPS may be out of adjustment bad sensor, bad connection, bad pcm as likely causes.

DEAR EXPERT

I'VE JUST EARASED THE TPS CODE AND ITS GONE
BUT STILL I HAVE CODE NO. 44 FOR IGNITION COIL & POWER TRANSISTOR UNIT SYTEM

I NEED THE TROUBLE SHOOTING PROCEDURE CUS I'VE REPLACED THE ENGINE MODULE, COILS, SPARK PLUGS, CAMSHAFT SENSOR AND CRANCK SHAFT SENSOR

THE STALL & CHECK ENGINE PROBLEM GOES OUT FOR TOW WEEKS AGO AND COME BACK AGAIN!

ALSO I INSPECT THE WIRING BUT STILL I HAVE NO SOLUTION!
ITS DRIVING ME CRAZY

IF THERE IS ANY PROBLEM INSIDE THE ENGINE MECHANICAL COULD CAUSE CODE 44?

My guess is that code will return, shouldn't erase.

Did you check the link I sent for the procedure?

Did you reprogram the pcm after replacement?

I don't expect a mechanical problem, but it is always possible.

Hi noor_hawamdeh,

If you count the blinks on the CHECK ENGINE light when bridging the 1st and 4th terminal of the OBD II diagnostic dats, then your codes are correct for checking engine.

If you use LED or voltmeter to couln the number of blinks, then you have gone into transmission diagnostic mode, which I believe you have got the data.

Engine and trans error code have different interpretation.

Code 14 = TPS error, voltage below 0.2 or more than 1.2 v at idling. (Improper TPS adjustment or faulty part)

Code 22 = Kickdown servo switch does no turn OFF when in 2nd or 4th gear. (Short circuit in kickdown servo switch)

Code 44 = Shift control solenoid valve B (SCSV-B) resistance is small. (Short circuit in SCSV-B)

If the engine stalls at idling while engaging D, most probably the trans needs to be rebuilt, there are internal wear. Drop oil pan and if you see metal filings, you would know what to expect.
