Motor Houd In Bij Vol Gas

[wimvanbeelen]

Van een yj 6 cilinder bouwjaar 1992 heb ik het probleem dat hij bij vol gas geven heel erg gaat inhouden tegelijkertijd gaat ook het motor management lampje branden.  Zodra ik het contact uit zet en weer start is het lampje uit.

[brandend zand]

Kennis heeft zelfde gehad, bij rustig gas geven geen last van. Bleek de bobine haarscheurtjes te hebben. Was wel een 1.7  motor.  Even controleren kan nooit kwaad.

Vacu

[schneiders]

Dat kan van alles zijn, ik zou ook de brandstofdruk checken is het brandstoffilter al eens vervangen de laatste tijd.

Eerst maar eens -laten- uitlezen he.

[DogJeeper]

Kun je een YJ uit 1992 uitlezen dan ?!  Ik dacht dat dit alleen via de contact aan-uit methode kon ?

[EJG]

katalysator, maar kan idd van alles zijn.

OBDI for Jeep YJ 1991-1995. 

Turn key on/off three times, then on (engine not running), engine light will flash codes. 

Longer pauses are breaks between codes. Last code will be 55. 

Ignore code 33 on non ac YJ's

11 No ignition reference signal detected during cranking OR timing belt skipped one or more teeth; OR loss of either camshaft or crankshaft position sensor. 

12 Battery or computer recently disconnected 

13 MAP sensor or vacuum line may not be working 

14 MAP sensor voltage below .16V or over 4.96V 

15 No speed/distance sensor signal 

16 Loss of battery voltage detected with engine running 

17 Engine stays cool too long (bad thermostat or coolant sensor?) 

OR 

17 (1985 turbo only): knock sensor circuit 

21 Oxygen sensor signal doesn't change (stays at 4.3-4.5V). Probably bad oxygen sensor 

22 Coolant sensor signal out of range - May have been disconnected to set timing 

23 Incoming air temperature sensor may be bad 

24 Throttle position sensor over 4.96V 

25 Automatic Idle Speed (AIS) motor driver circuit shorted or target idle not reached 

26 Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors) 

27 Injector circuit isn't switching when it's told to (TBI) 

OR (MPI) injector circuit #1 not switching right 

OR (turbo) injector circuit #2 not switching right 

OR (all 1990-) injector output driver not responding 

- check computer, connections 

31 Bad evaporator purge solenoid circuit or driver 

32 (1984 only) power loss/limited lamp or circuit 

OR 

32 EGR gases not working (1988) - check vacuum, valve 

OR 

32 (1990-92) computer didn't see change in air/'fuel ratio when EGR activated - check valve, vacuum lines, and EGR electrical 

33 Air conditioning clutch relay circuit open or shorted (may be in the wide-open-throttle cutoff circuit or normal on early 80's models if you don't have air conditioning) 

34 (1984-86) EGR solenoid circuit shorted or open 

OR 

34 (1987-1991) speed control shorted or open 

35 Cooling fan relay circuit open or shorted 

OR 

35 idle switch motor fault - check connections 

36 (turbo only) Wastegate control circuit open or shorted 

37 Shift indicator light failure, 5-speed 

OR 

part throttle lock/unlock solenoid driver circuit (87-89) 

OR 

solenoid coil circuit (85-87 Turbo only) 

OR 

Trans temperature sensor voltage low (1995 and on) 

41 Alternator field control circuit open or shorted 

42 Automatic shutdown relay circuit open or shorted 

OR 

42 Fuel pump relay control circuit 

OR 

42 Fuel level unit - no change over miles 

OR 

42 Z1 voltage missing when autoshutdown circuit energized (The Z1 voltage is the voltage of the circuits fed by the autoshutdown relay. This typically includes fuel pump and switched-battery feed to the ignition coil) 

43 Peak primary coil current not achieved with max dwell time 

OR 

43 Cylinder misfire 

OR 

43 Problem in power module to logic module interface 

44 No FJ2 voltage present at logic board 

OR 

44 Logic module self-diagnostics indicate problem 

OR 

44 Battery temperature out of range 

45 Turbo boost limit exceeded (engine was shut down by logic module) 

46 Battery voltage too high during charging or charging system voltage too low 

47 Battery voltage too low and alternator output too low 

51 Oxygen sensor stuck at lean position (this may be tripped by a bad MAP sensor system causing a rich condition. If you get hot rough idle and stalling, especially on deceleration, accompanied by flooded engine and difficulty restarting, that can be a bad MAP sensor causing the O2 sensor to try to compensate. If you get poor cold driveability, stumbling and bucking, and acceptable warm driving with poor gas mileage (a drop of 10 mpg or more), that is usually the O2 sensor. 

OR 

51 Internal logic module fault ('84 turbo only). 

52 Oxygen sensor stuck at rich position 

OR 

52 Internal logic module fault ('84 turbo only) 

53 Logic module internal problem 

54 No sync pickup signal during engine rotation (turbo only) 

OR 

54 Internal logic module fault ('84 turbo only) - or camshaft sensor/distributor timing 

55 End of codes 

61 "Baro" sensor open or shorted 

62 EMR mileage cannot be stored in EEPROM 

62 PCM failure SRI mile not stored 

63 Controller cannot write to EEPROM 

64 Catalytic converter efficiency failure 

65 Power steering switch failure

 

 

 

Succes!  Rij anders even langs Ruud v. Beelen (4x4Katwijk) hij kan je misschien verder helpen.

Met de DRB2, uit mijn hoofd zit er een twee polige stekker onder de motorkap

[Ab]

Heb je deze twee stekkers naast de accu zitten?  Normaal zitten er  gele rubberen kapjes over.....

 

 

 

 

 

Dat is de OBD1 diagnose stekker, uit te lezen met de DRB2 scanner.

Die ja, iets meer dan 2 polig , ik was in de war met de VW auto groep
