    p0202 fault. # 2 inj circuit. inj ohms good, all of them. plugs good. no other faults. in process of checking injs for sound of firing with screwdriver to ear. feels like something cutting power to ignition system on and off quickly over and over until you let off accelerator. no problems unless accelerating, at all. no miss in engine. runs perfect unless you accelerate . trouble at about 35 and 75 accelerating mostly. have worked on my cars 30 years, not seen this symptom before. thank you for your help. have scan tool and books and online info access on this car. trying to help my sister out with her car. thank you for your assistance. jim

    2004 sebring convertible 2.7 shows p0202 fault, #2inj circuit fault, difficulty accelerating , minor jerking low speeds, major major jerking and bucking high speeds, 75-80mph. only one fault. injs all ohm good. wiring looks good, and plugs. renewed plugs. no help. now checking injs more closely for firing in idle. scan tool shows fuel loop 2 opens when fault sets, closed previously. fuel loop 1 stays closed. smooth as silk unless accelerating. if careful i can get to 77 mph smoothly but then it jerks like its going to fly apart. will one inj produce these symptoms or do you think something more serious? working on injs today to remove this fault. i am thinking now maybe it is just an inj or no pulse to it. ???? this high speed reaction i have not seen before in 30 yrs working on my own cars. have access to all web info alldata and books also. thank you for your assistance. trying to get my sisters car fixed. grace and peace. jim

    what feedback is the pcm seeing that tells it to set p202 fault? how does it know #2 inj circuit is faulty? is it simply seeing an open circuit on 2 inj inside the pcm or is there an external sensor causing this fault to set? thank you very much. jim

Is your check engine light on? This problem could be several different things. The jerking sounds like spark plugs not firing. Can you please give me more information? What kind of car? What engine?

1995 jeep grand cherokee laredo jerking at 50 mph


which engine? (asked now 1000 times, only 2 ever answered)

tune up time, spark parts, rotor to plugs. filters. both.

its called a 60k mile tune up solves most.

my guess, is its misfiring or

is this the ASD relay dropping out then back in, as driven.

jerked before and after CKP sensor, did you know its the last thing to fail......

see the list of ASD drops.

misfiring, can be felt, its like a misfiring chain saw, ever here a 2 stoke misfire, ratta, tata ,tat?

some call it jerking, its not, is misfiring. (3reasons ) and 25 causes.

but jerkin real, like if you cut the ignition that is and instant bog.

but if you off the key and back on , fast, that be a jerk

that is total power loss. not misfire. its loss spark and fuel.

and jerks hard.

so does loss of 12vdc to the EFI system.

so the first step is to see if its the ASD relay dropping out.

on all jeeps.. 93 to now.



ASD



http://www.fixkick.com/Jeeps/ASD.html



automatic, shut down. (relay and EFI logic)



key point, the ASD will kill the engine, if fit sees spark is bad.

so its a chicken and egg deal.

here is the logic.

key on , crank , ASD closes, fuel injects and engine starts

then dies in seconds. or runs full time.

note that if the ECU sees spark dead, it cuts spark.

Sounds odd , huh. but is NOT.

this relay stops all car fires. (caused by this protection not in place)

Car jerking at low speeds and idle


Not fuel filter. Is your engine light on? Could be accelerator pedal position sensor. Does it do it only when you are accelerating?

What is ASD RELAY


The power supplied to the fuel pump, ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.



The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module. This causes the engine to shut down.


Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

Transmission jerks on 1985 Crown Vic when cold. Doesn't want to shift, and transmission jerks violently when cold. Also, automatic transmission doesn't like to shift into 3rd gear, unless you exceed 45...


Unless you are low on fluid, I suspect you are in need of a rebuild. I have had similar problems before. Any shop will tell you to try a fluid and filter change. It has never brought one of mine back. I would suggest adding fluid to the top of the 'add fluid' area of the dipstick and no more. It can foam if it is to full, causing similar problems as being to low. I would add that if you have to replace the transmission - you need to consider that the car may not be worth the cost.
Good Luck.

No start...2000 Wrangler 4.0liter, automatic.


To me it sounds like you have weak battery. Hook up a meter and check voltage. should be over 12v, then turn key on. should maintain 12v. then crank. If the voltage goes below 11v cranking the battery is bad. Be sure to test the battery. Not the cables. Then tst the cables. You may have good voltage just touching the battery and you may have low voltage touching the terminals which would indicate a dirty connections.

Engine won't start


Sounds like an AUTOMATIC SHUTDOWN (ASD) RELAY problem. Fairly common on the Caravan.
Heres a brief overview of the ASD.
The Powertrain Control Module (PCM) operates the Auto Shutdown (ASD) relay by switching the ground path on and off.
The ASD relay supplies battery voltage to the fuel injectors, electronic ignition coil and the heating elements in the oxygen sensors.
The PCM controls the relay by switching the ground path for the solenoid side of the relay on and off. The PCM turns the ground path off when the ignition switch is in the Off position unless the 02 Heater Monitor test is being run. Refer to On-Board Diagnostics. When the ignition switch is in the On or Crank position, the PCM monitors the crankshaft position sensor and camshaft position sensor signals to determine engine speed and ignition timing (coil dwell). If the PCM does not receive the crankshaft position sensor and camshaft position sensor signals when the ignition switch is in the Run position, it will de-energize the ASD relay.
The ASD relay is located in the Power Distribution Center (PDC). The PDC is located on the driver's side inner fender well Power Distribution Center . A label on the underside of the PDC cover identifies the relays and fuses in the PDC
Check for good ground.
Good luck...i hope this helps, please rate me a fixya.

try a rebuild kit for your carb, you have trash inside it. I had the same problem with my blazer and that fixed the problem.
