Replace the pressure control solenoid on the transmission, is it shifting hard??
Its located underneath the side cover of the tranny. You may have to lower the sub frame to gain clearance to get the cover off, then its easy.

Those a not OBD trouble codes. OBDII trouble codes start with a P and are followed by four numbers. P0305 would be a proper trouble code.

I need the trouble codes for 1995 kia sportage 4wd 2.0 i just need to see what they are, ive been all over the web and keep getting nowhere thanks for your time


Trouble code definitions do not necessarily have to be under the "Kia" heading; imports share trouble code definitions and are identical in most cases. Very rarely is a trouble code brand-specific. Check under Hyundai and Mitsubushi and you will see that Japanese and Korean car companies have similiar trouble code definitions.

Note: You have 1995 model year; this could be more challenging since most OBD-II systems started from 1996 and on.

My '93 suzuki sidekick automatic transmission 4 wheel drive after warm up "overdrive off" starts flashing on and off and when on the drivetrain stops working


The O/D light's flashing means there is some kind of transmission trouble.

The codes are..


Trouble Code (1) Probable Cause
12 ............................... System Operation Normal
21 ..................... No. 1 Shift Solenoid Open Circuit
22 .................... No. 1 Shift Solenoid Short Circuit
23 ..................... No. 2 Shift Solenoid Open Circuit
24 .................... No. 2 Shift Solenoid Short Circuit
25 ............................. TCC Solenoid Open Circuit
26 ............................ TCC Solenoid Short Circuit
31 ............ Vehicle Speed Sensor Open Or Short Circuit
32 ................ Throttle Position Sensor Short Circuit
33 ................. Throttle Position Sensor Open Circuit
34 ................ Defective Park/Neutral Position Switch
36 .............. (2) No Signal-Both Vehicle Speed Sensors
(1) - Check listed component for probable cause. Also check wiring and connections of specified component.
(2) - No signal from both transmission and speedometer mounted vehicle speed sensors.

If a trouble code is present, OD OFF light will flash a trouble code. The number of flashes will equal first digit of trouble code. After a one second pause, second digit will be displayed. If more than one trouble code is present, next trouble code will be displayed after a 3 second pause. Smallest number trouble code will be displayed first. Trouble codes will be repeated.

Hope this gave you some insight on the issue.

Our 2005 Pontiac Grand Prix is hard shifting. The diag codes that came up are trans codes P1811c and P1819c. Does anyone know what these codes mean? I'm having an impossible time finding them. Thanks in...


The codes mean that the Electronic Pressure Control Solenoid is going bad. The computer detects that the shifts are taking longer than 0.65 seconds. Then the computer commands maximum line pressure to avoid burning out the clutches, hence the hard shifting. My 2002 Grand Prix had the same problem, and I had great luck just installing a shift kit to speed up the shifting and haven't had any further issues.

Air bag sensor keeps flashing


If a concern is detected, the air bag control module will communicate by flashing the warning indicator. A diagnostic trouble code (DTC) is logged by the air bag control module in a nonvolatile memory. For additional information, refer to Diagnosis and Testing in this section.
Lamp Fault Codes (LFC)
Item Part Number Description 1 One flash cycle: Driver air bag trouble code 2 Two flash cycle: Passenger air bag trouble code 3 Three flash cycle: Trouble code common to both driver and passenger air bag circuit 4 Four flash cycle: Safety belt pretensioner trouble code common to both driver and passenger pretensioner circuits 5 Five flash cycle: Driver side air bag trouble code 6 Six flash cycle: Passenger side air bag trouble code 7 Not used 8 Not used

Airbag flashes 10 times misses a flash then repeats


Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

---------------------------------------------------------------------
Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.
  • Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
  • If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
  • If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.
Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.
  • If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
  • If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.
Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.
  1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.
  1. Cycle the ignition switch to OFF and then to RUN.
  1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
  1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).
  1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
