Question about 1984 Cadillac Eldorado

1 Answer

Clearing diagnostic codes

I am unable to clear code 27 (TPS) by pushing the "OFF" and "HI" buttons on the ECC. I replaced the TPS last year. The car only has 54,000 original miles, and is running great. Do I need to replace the TPS, just to get that annoying light turned off.

No you might have to get someone with an OBD hand held (on board diagnostic) computer and clear codes that way

1999 Dodge/cummins can the P0122 code cause my hard start problem


this obd2 trouble code table can help you understand the meaning of code, for this code, you can try:
Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

this code may cause by:

TPS not mounted securely.

TPS circuit short to ground or another wire.

Faulty TPS.

Damaged computer (PCM).

to fix this code you can try this:


Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.

Is there a certain way to install the tps sensor on a 1987 nissan pathfinder. do you need to clear the codes before or after install.


Should be no code clearing on any TPS install I am aware of.
In a couple days,on this site, I may learn otherwise.
The code issue, is only when a sensor goes out of range,and that doesn't mean they are bad or get replaced.

P0122 and po700


HI. Lets start with the P0122 Code.

This code is in reference to the TPS(Throttle Position Sensor). A P0122 code essentially means that the the vehicles computer has detected that the TPS is reporting a low voltage condition. On some vehicles, the lower limit is 0.17 - 0.20 volts, respectively. This can occur if the TPS was not recently installed correctly or mis adjusted. If you have not installed it recently, than the most likely actions are to replace it, asap. Here are the most common symptoms listed below:

1. Rough idle
2. stalling during acceleration or stumbling at a red/stop light.
3. poor acceleration

If you are not experiencing those symptoms, it will most likely be intermittent and clearing the code may resolve the problem for a short time. If this should be the case, i would check the wires for rubbing against the housing or grounding faults. Again, make sure it is adjusted properly if recently installed.


The next code will be the P0700.

This is a serious transmission control unit code. You will need to take this vehicle to the dealership for the correct scan tool. You will need to extract the special codes to actual repair, correctly. Usually, the entire module will need to be replaced. A regular scanner will not pick up the TCU codes. This is a dealership code. Most Kia's are covered with a 10 year/100,000 warranty, so this should be covered.

Can i recive codes from my climate contral panel on a 1996 caddy


To check the computer for CODES:
1. Ignition switch ON. Engine OFF
2. Simultaneously push and hold the OFF and WARMER buttons on the climate control panel for 3 seconds and release them
3. See if you get codes such as AC1347 or AC1348 or some other LETTER/NUMBER combination display on the fuel data display along with HISTORY or CURRENT with each code or codes that display...
- AC1312 = AC high side temp sensor has an open circuit.
- AC1314 = Evaporator inlet temp sensor has an open circuit.
- AC1348 = Very low AC refrigerant condition.

Try addind about 1/2 can of freon to the system and see if the compressor engages. If not, you will need to perform some diagnostic tests on the above codes. I can e-mail you the pictures and directives on how to fix the codes, But first you need to clear (ERASE) the codes from the computer and see which codes return as current or history codes which should display just after each code.

4. After the code or codes display you will see PCM?
5. Turn ignition OFF.

To clear the codes:
1. Re-enetr diagnostics like you did before and when you see PCM?
2. Push and release the LO button and you will see IPC?.
3. Push and release the LO button and you will see ACM?.
4. Push and release the HI button and you will see ACM CODES?
5. Push and release the LO button and you will see ACM CLEAR CODES?
6. Push and release the HI button and you will see ACM CODES CLEAR.
7. Turn OFF ignition key and wait 2 minutes and re-enter diagnostics like I told you in the previous e-mail and let me know what codes appear and if they are CURRENT or HISTORY.

Hope helped.

Howdo i enter diagnostic mode 1994 deville


TROUBLE CODE DISPLAY:
After entering On-Board Diagnostics, a segment check is automatically performed and then any trouble code stored in computer memory will be displayed. Codes may be stored for the Powertrain Control Module (PCM), Instrument Panel Cluster (IPC), Air Conditioning Programmer (ACP), Supplemental Inflatable Restraint (SIR), Traction Control System (TCS) or Road Sensing Suspension (RSS) systems.
Each trouble code consists of the system abbreviation: (E: Engine, PCM), (I: IPC), (A: ACP), (R: SIR), (T: TCS), (S: RSS), a three digit code identifier, and the letter C or H. All codes for each system are displayed together, in the order of their three digit number (lowest first). The final digit of the code, a "C" or "H" is used to indicate whether the code is Current or History. A "C" means the fault was still present the last time the diagnostic test was run, while "H" means the failure was not present the last time the code was tested for.
If no codes are present for a system, a "NO X CODE" message (with "X" being the system i.e. E, I, A, R, T or S) will be displayed. If the communication line to a component is not operating, a "NO X DATA" message will be displayed, indicating that the IPC could not communicate with that system.
SELECTING THE SYSTEM:
After trouble codes have been displayed, a specific vehicle system PCM, IPC, ACP, SIR, TCS, RSS may be selected for testing.
The first available system will be automatically displayed (i.e. PCM?). While selecting the system to test, any of the following actions may be taken:
  1. Depressing the "HI" button on the CCC will select the displayed system for testing.
  2. Depressing the "LO" button on the CCC will display the next available system selection. This allows the display to be stepped through all system choices. This list of systems can be repeated following the end of the system list.
  3. Depressing the "OFF" button the CCC will stop the system selection process and return the display to the beginning of the trouble code sequence.
SELECTING THE TEST TYPE:
Having selected a system, the first available test type will be displayed (i.e. PCM DATA?, PCM CLEAR CODES?). While selecting a specific test type, any of the following actions may be taken:
  1. Depressing the "HI" button on the CCC will select the displayed test type. At this point the first of several specific tests will appear.
  2. Depressing the "LO" button on the CCC will display the next available test type for the selected system. This allows the display to be stepped through all available test type choices. This list of test types can be repeated following the display of the last test type.
  3. Depressing the "OFF" button on the CCC will stop the test type selection process and return the display to the next available system selection.
CLEAR CODES
Selection of "CLEAR CODES?" test will result in the message "CODES CLEARED" being displayed along with the selected systems name. This message will appear for 3 seconds and then return to the next available test type.
EXITING DIAGNOSTIC MODE:
To get out of the diagnostic mode anytime during the test, depress the "AUTO" or "DEFOG" button, or turn the ignition switch "OFF." Trouble codes are not erased if this is done prior to selecting "CODES CLEARED."
ECC Trouble Code Descriptions:
  • DTC A010 - Outside Temperature Sensor Circuit
  • DTC A011 - High Side Temperature Sensor Circuit
  • DTC A012 - Low Side Temperature Sensor Circuit
  • DTC A013 - In-Car Temperature Sensor Circuit
  • DTC A015 - Sunload Sensor Circuit
  • DTC A037 - Loss of IPC Data
  • DTC A040 - Air Mix Valve (Door) Circuit Problem
  • DTC A047 - Low Refrigerant Charge
  • DTC A048 - Low Refrigerant Pressure
  • DTC A050 - HVAC - Coolant Temperature Too High

I have 3 ipc codes what does ipc stand for 98 cadillac eldorado


IPC stands for Instrument panel control, here is a typical code repair flow chart, this is for example only and has nothing to do with your car..
P083 = 24x signal high.

P107 = Instrument panel control )IPC) to computer (PCM) data problem.

P137 = Loss of Automatic braking system (ABS) to Traction control system (TCS).

What you need to do is CLEAR all these codes from the computer and see which ones return.

Perform this test.

1. Ignition key ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER (^) buttons on your climate control panel for 3 seconds and release them.

3. Diagnostic codes such as above will appear with the word HISTORY or CURRENT for each code.

4. The codes will stop when you see PCM?

5. Push and release the HI(^) button and you will see PCM DATA?

6. Push and release the LO(v) button and you will see PCM DATA?

7. Continue to push and release the LO (v) button until you see PCM CLEAR CODES?

8. Push and release the HI(^) button until you see PCM CODES CLEAR.

9. Turn OFF the ignition and wait 3 minutes and try and start the car. If the car starts and the light comes back ON, Turn OFF the car and repeat steps 1 thru 3 and let me know what codes you get and if they are HISTORY or CURRENT.

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.
