CODIGOS DE FALLA EN LAS XJ
por EDUHXJ-15 el 9/4/2008, 11:12 pm
Para ver los codigos lo que tienen que hacer es:
*meter la llave y pasarlaa ignition y en 5seg darle 3 veces, osea
(on,off,on,off luego on y dejar la llave en la posicion de off)
*luego mirar la luz del check engine (tiene forma de motor) y esta vaa
parpadearrapidamente con pequeas pausas
(cada flash es un numero, el primero del codigo) luego hay una pausa
intermedia que indica el segundo numero media el flash.*Luego de esto hay una pausa grande donde viene el proximo codigo.
Por ejemplo si les digo que tengo el codigo 55 lo leeriamos de la siguente
forma:
5 flashes rapidos.......una pausa media y luego 5 flashes rapidos
espero les sirva
Code Description Most likely reason
11 No crank signal to computer Fault in wiring between crankshaft position sensor
(CPS) and ECM ( PCM or computer ) or faulty CPS.
12 Battery disconnected Battery or power to the ECM disconnected in the last 50
key cycles.
13 MAP Sensor No change in Manifold Absolute Pressure (MAP) between engine off
and on. Check circuit and MAP sensor.

the key into the on position m 0 king s 1 2 e not to start it while these terminals are
connected at any time. It should flash the code 12(1 flash, pause, 2 flashes)
three times in a row and will repeat thissequence until disconnected if no other
codes are recorded. If there are any faultsstored then they will follow afterwards
repeating themselves three times before moving on to the next code. To clear to
codes remove negative cable for 10seconds or longer.
Code Description Most likely reason
12 Terminals6 and 7connected. If appears when terminals not connected and
engine running, no signal between distributor and computer.
13 Oxygen sensor circuit. Check TPS adjustment. Check O2 wiring and sensor.
14Coolant sensor circuit. Overheating or fault in wiring or coolant sensor.
15Coolant sensor circuit. Low temperature or fault in wiring or coolant sensor.
21 TPS circuit. Signal voltage high. Check TPS and adjustment. Also wi ring at both
computer and TPS ends.
23Mixture control (M/C). Check wiring at M/Csolenoid and computer. Clear code
and re-check after driving.
34MAP sensor. Check wiring and hose in case of leak. Otherwise replace.
41 No distributor signal. Check distributor wiring and pick-up coil connections.
42 EST or bypass problem. Check wire to terminal 12 on ECM or faulty HEI module
can cause same code.
44 Lean exhaust. Check for sticking M/Csolenoid also terminals 9 and 14 at ECM.
Vacuum leakage or faulty O2sensor.
44-45 O2sensor or circuit. O2circuit wiring or sensor faulty.
45Rich exhaust. Check for sticking M/Csolenoid and wiring pluscharcoal canister
for fuel. O2sensor faulty.51 PROM fault. Needsspecialist or dealer diagnostics.
54M/Csolenoid Check wiring at M/C and ECM. Faulty M/C.
55Reference voltage. Check short to ground on ECM terminal 21 wire. O2sensor or
ECM faulty

duda
por blitoso el 10/7/2008, 10:14 am
estimado EDUHXJ-15 en casa poseemos un cherokee 91 limited sinc (motor
relativamente nuevo).. tiene como 2 meses con una falla toda eVtraa cuando
prende fulll humo y de pronto se le kita y no falla.. pero la apagas y al
prenderla asi sea un minutoWue la de
X
aste apagada hace lo mismo.. cuando
se compro nos dimos cuentaWue uno pasa la suichera a
X
a varias veces y te
da los codigos pero no sabia los codigos hasta hoyWue vi este foro
Wue
publicaste... me fui pa la burra y esteeeee... le di a la suichera y nananai
nananai... W ue podria ser...??? sera W ue la compu esta loca (fundida)??? ya
he revisadoWue no tenga entradas de aire y tal pero aca no hay nadie con
escanner... en agosto esWue va para valenncia y se va a revisar peropor
ahoraWueria ver hasta
Wue punto puedo revisar... ehh alguien sabe como
resetearla...
P.D. seraWue la computadora no es para cherokees negras con asientos
grices? nooo no debe ser porWue la camioneta siempre ha sido negra.... eh la
comanche no echa mas broma con la computadora...
