P1294 WHAT ENGINE? target idle not reached, (means idle is wrong)
4.0L or 4.7L

means the ISC was changed by the PCM (commanded) and the ISC
failed to adjust idle to the correct speed.
clean the throttle bore.
clean the ISC.
or find intake leaks.

see chapter emissions here.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service


it means IDLE controls are out of control.
only that. and many things can cause that.
lean fuel mixture, gross misfire.
ISC unplugged?
a tech, checks all these things. the engine is running right
and when sure the engine is right, and holds closed loop at idle !!!
then and only then start testing the ISC.
we make sure it can move through its range.
and that the throttle plate is not blocked. for (any reasons)
and then make sure there are no vacuum leaks.
on MAP based systems, any air leak cases the engine to race
and if bad enough the ISC fails to work right. (for sure)
those are the hit lists. the tests are extensive.

SOURCE: Target Idle Not Reached (Chrysler, Jeep)

The code P1294 means that the computer is setting a target for the engine to idle at and the engine cannot do it therefore setting the DTC. Solution start by checking or replacing the sparkplugs. Also remove the idler motor from the throttle body and spray it out with carb cleaner. Also spray out the passages in the throttle body that the idle motor use. If that does not fix it you could have another problem like a bad idle motor or something relating to that circuit. Did you replace the TB or make an adjustment to the TPS?

CAN YOU PLEASE TELL ME WHAT THIS CODE MEANS P1294 FROM A SMOG CHECK ON A 1997 DODGE STRATUS


The code is "target idle not reached". This indicates that the idle is too fast and this is what sets the code. The cause could be the TPS or the IAC, but normally if these were the problem, you would have additional codes to indicate them.. The P1294 without any other code is most likely going to be caused by an intake leak, one that occurs after the MAF sensor if your car has one, or the throttle body if not.

High rpm at idle: code P1294 target idle not reached


Hi Rodrigo, The idle control is activated by the temperature sender unit. It sounds as though yours is giving a cold signal to the computer and it pushes up the idle speed to compensate as if it has just started. The sender unit is a different unit from that which operates the gauge on the dash instrument panel. Replace it and I believe your problems will be over.Regards John

1996 dodge caravan 2.4 code p1294


on dodge motors
fitted a lot of parts and still no better

the fault code clears and comes back as a intermittent problem

could be electrical voltage drop off or heat related failure

i wonder if your 02 sensor ,the catalytic converter
or other related sensors
are causing the fault to come back
if needed .....fit a new air filter...

how the test is determined

P1294-TARGET IDLE NOT REACHED 3.3L/3.8L
When Monitored and Set Condition:
P1294-TARGET IDLE NOT REACHED 3.3L/3.8L
When Monitored: With the engine idling and the transmission in drive, if automatic.
There must not be a MAP sensor trouble code or a Throttle Position Sensor trouble code.
Set Condition: The engine idle is not within 200 rpm above or 100 rpm below the target
idle for 40 seconds. One trip fault.

POSSIBLE CAUSES
INTERMITTENT CONDITION
IAC MOTOR PASSAGES
VACUUM LEAKS
AIR INDUCTION SYSTEM
THROTTLE BODY AND THROTTLE LINKAGE
TEST ACTION APPLICABILITY

What does the P1294 Manufacturer Specific Code mean in a failed Emissions OBD Test?


P1294 Target idle not reached this is the code in the chrysler list of codes for this number and reading it ,it must mean the idle isnt correct when engine is warm but i could be wrong here in my interpretation as our europeon test puts a probe up the exhaust and the idle doesnt come into the equation .So long as the gas output from the engine is below the specified limits on first run at 2500 rpm then idle is read but this is only for the CO and oxygen levels in the exhaust gas as the level of CO2 will depend on the size of the engine but must be below 2% on idle ,so a big monster american gas burner will still be below the 2% by volume on idle but rise with the increase in engine RPM .Complicated business and costly when the cat goes

Code p1294 03 sebring


P1294 verbiage is simply "Target Idle Not Reached (+/-200 RPM)" which unfortunately is one of the DTC's that is least helpful. The most likely cause of this is a simple vacuum leak, very possible a leaking gasket at the base of the throttle body. What happens is unmetered air enters the engine confusing the PCM, forcing the IAC to chase the idle speed up and down. The first thing you should do is look under the hood and verify that all of the vacuum hoses are connected and in good shape, the brake booster isn't leaking and finally get a can of carb cleaner and go hunting for a leak. If you haven't done this before I recommend letting someone who is comfortable with the procedure do it for you or show you how.
