Check Engine Light '98 Grand ES - Posted: 04-24-2006, 07:22 AM
First of all, I'd like to thank all the help this forum offers, and it's been possible only by people like yourself reading this post. Thanks!
Here's a historical rant before I go into questions: "I have a '98 Grand ES which I recently took to the dealship we bought the vehicle from to replace/troubleshoot the cooling fans. Anyways, after paying them good money for a new cooling fan relay, I found the problem was not fixed as I stood in a rush-hour traffic jam with my baby in the back seat
Since then I concluded the fans do work, and I placed a switch on the van so I can now control the cooling fans myself. "
Anyways. The "check engine light" is showing on my van. It started showing a week or so after the dealership "worked" on the van, and it still shows today.
The instrumentation diagnostic shows "Check 0," but it then never shows "Check 1." Should it show "Check 1" after showing "Check 0?"
Also, I cannot get the van to run the Diagnostic Trouble Codes (DTC's), only the instumentation diagnostic.
How do I get the van to run the DTC's? Everytime I follow the routine I only get the "Code 999, Check 0" which I assume is the instrumentation diagnostic.
Also, is there a way to reset the "Check Engine Light?"
I've checked ALL the fuses, inside and under the hood, so a blown fuse can be eliminated as the cause of these problems.
Thanks for your help!

You can try the key ON-OFF method
Turn the key ON-OFF, ON-OFF, ON-OFF three times and ending in the ON position but don't start the engine. Watch the check engine light it will flash (2) digit codes.
example a code (12) will be one flash followed by a pause then 2 flashes and so on.
The 1998 Caravan does the same check engine light code trick, but it also does an instrument diagnostic check if you hold the trip and reset buttons and turn the key to the run position and wait 5 seconds.
Below is a list of codes, its not complete but it a place to start.
11 No ignition reference signal detected during cranking (bad Hall effect) OR timing belt skipped one or more teeth; OR loss of either camshaft or crankshaft position sensor. Can cause the engine to stop working entirely with no limp-home mode.
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?)
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 (SEE NOTE #3)
25 Automatic Idle Speed (AIS) motor driver circuit shorted or target idle not reached, vacuum leak found
26 Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors) (SEE NOTE #4 BELOW)
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
32 EGR gases not working (1988) - check vacuum, valve
32 (1990-92, all but Turbo) 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)
34 (1984-86) EGR solenoid circuit shorted or open
34 (1987-1991) speed control shorted or open
35 Cooling fan relay circuit open or shorted
35 (trucks) idle switch motor fault - check connections
36 (turbo) Wastegate control circuit open or shorted
36 (3.9/5.2 RWD) solenoid coil circuit (air switching)
36 (Turbo IV) #3 Vent Solenoid open/short
37 Shift indicator light failure, 5-speed
part throttle lock/unlock solenoid driver circuit (87-89)
solenoid coil circuit (85-89 Turbo I-IV)
Trans temperature sensor voltage low (1995 and on; see NOTE 2)
41* Alternator field control circuit open or shorted
42 Automatic shutdown relay circuit open or shorted
42 Fuel pump relay control circuit
42 Fuel level unit - no change over miles
42 Z1 voltage missing when autoshutdown circuit energized (SEE NOTE #6)
43 Peak primary coil current not achieved with max dwell time
43 Cylinder misfire
43 Problem in power module to logic module interface
44 No FJ2 voltage present at logic board
44 Logic module self-diagnostics indicate problem
44 Battery temperature out of range (see Note #1!)
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 (Bob Lincoln wrote: may be tripped by a bad MAP sensor system causing a rich condition, and the O2 sensor trying to compensate. The O2 sensor may still be good. The MAP assembly consists of two pieces, the valve and the vacuum transducer (round plastic unit with cylinder on top and both electrical and vacuum connections) - 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. [Webmaster note: MAP sensors seem to die regularly.]
51 Internal logic module fault ('84 turbo only).
52 Oxygen sensor stuck at rich position (SEE NOTE #5!)
52 Internal logic module fault ('84 turbo only)
53 Logic module internal problem
54 No sync pickup signal during engine rotation (turbo only)
54 Internal logic module fault ('84 turbo only) - or camshaft sensor/distributor timing (7)
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
Below is a list of ODBII codes used on late 90's and up caravans, these usually start with a P and then the code exp (P-1234)
To get the codes, put the key into the ignition, push down the odometer reset button, then turn the key to RUN with your finger on the button - and then release the button. The odometer will go through 1111111 through 999999, then display the car's serial number, then show the error codes starting with P. I'm not sure what the other displays mean. Note that this method may not work with 2003 or later vehicles.
