Fault symptoms

• CHECK ENGINEIdles rough and stalls code - 2_bing.gif lights up straight away.
• Throttle control in limp-home mode.
• Incorrect idle speed.
Cruise control2_bing.gif inoperative.

The following conditions apply for this DTC:

• Engine running.
• Car is moving.
• Throttle motor is receiving 100% PWM in closing direction.

Or:

• Less than 5 seconds since engine was started.
• Throttle motor is receiving 100% PWM in closing direction.

A mechanical fault is preventing the throttle from closing.

Important

The diagnostic trouble code can be generated if the
throttle mechanism has not been properly reset after
activation of the limp-home solenoid.

Check the wiring

Jiggle the leads and in-line connectors at various points
and in different directions to detect any intermittent
breaks or short circuits in the wiring. Observe the
multimeter, test lamp or diagnostic tool while doing this.

2004 Explorer Replaced Alternator, but car idle still not right, stalls, ck engine light still on. Car lights when dim and then car died. Mechanic said it was the alternator. Alternator replaced. Car...


You need to put a scanner on the truck and see if any codes are set and if so of course repair them and then clear the codes in the computer with the scanner. I would check the idle air control and the throttle position sensor. I would also check the alternator by starting the truck and then taking off the positive battery cable and the truck should continue to run. If not the alternator that was put on is bad.

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.

idle for 40 seconds. One trip fault.

POSSIBLE CAUSES
INTERMITTENT CONDITION
IAC MOTOR PASSAGES
VACUUM LEAKS

THROTTLE BODY AND THROTTLE LINKAGE
TEST ACTION APPLICABILITY

1999 M-B E320 drives great for about 5 or 600 miles then as i'm driving the check engine light comes on and the car looses power and idles rough like it wants to stall.It does not stall though.We


When the check engine light is turned on by the powertrain control module (computer) a fault code is stored to record what it is that caused the fault, in order to begin the process of diagnosis of this problem you have you must have the control module scanned for the stored codes.

Coming to stop eng light comes on for split second motor almost stalls than motor surges up returns to normal but sometimes stalls.when it stalls out it starts back up and light goes back out. thanks Bill


Is the check engine light on? If so, have the fault codes read with a scan tool. Most autoparts stores provide this service at no charge. It sounds to me like a faulty throttle position sensor, but it could be something else. The codes will tell you more surely where to begin looking. Hope this helped.

Rough idle


I had the same exact problem on my 2004 Colorado (3.5L). Cleaned the MAF sensor (with MAF sensor cleaner) and throttle body/plate - cleared it right up.
