Question about 1995 Buick Regal

Open Question

I used a obd1on my 95 buick reg and it came up with 3 codes 1.

I used a obd1 and it came up with 3 codes 1. p1361 electronic spark timing signal not switching after enable.
2.p0321 ignition/dist speed input enguine circuit range performance
3.p1670 qdm 4 failure
so im just tryiing to figure out what this mean's and how i can fix it, any idea's?

Does anyone know97 Honda Odyssey with code P1361 Tdc?


P-Power Train
1-Manufacturer Specified Code (Honda)
3-Ignition System, Misfire
6-Component or Sub-System Section
1-Component or Sub-System Section

P1361 is: Intermittent Interruption In TDC 1 Sensor Circuit.
Check out the TDC sensor, connector 124 (grey and on the distributor) check power and grounds. It's missing a signal from the TDC sensor in the distributor and causing a misfire.

P1361 code on 1999 buick park avenue


Code 1361 is a problem with the ignition module. The module would need to be tested.

I have a 95 buick le saber 3.8 ltr. It back fires when running. But when check engine light is on it wont back fire. It does sound louder with check engine light on. Changed coils. I need help trying to...


You need to scan the computer for trouble codes. If the light was on, there must be codes set. On a '95 Buick, it would be OBD-1, On Board Diagnostics-first generation ('96 and later is all OBD-2).
The diagnostic connectors are different for OBD1 and OBD2, but in '94 and '95, GM was on some models using a "hybrid" diagnostic link connector. You will just have to find the right diagnostic connector to get your codes. The guys at autozone or a national parts store who do engine scans for free may help you figure it out. If it is a straight forward OBD 1 connector, a cheap code reader could scan for trouble codes. For the OBD1, you can also use a jumper wire between terminals
A & B of the diagnostic link connector. Turn key to on, and two digit codes will begin to flash on the check engine light. Code 12, for instance, would be a flash, pause, two short flashes, and longer pause before the next code appears. Code 12 by the way, just means that the computer is in diagnostic mode-after that any set codes will appear or be flashed. Code 55 may also be flashed-this code means the end of codes that are set.

Is there an ALDL port on a legend ...to plug in a scan tool


There is a connector but it is not like the connector used in the newer 1996 OBD2 cars, your year uses OBD1, here is how you check for codes in this car.

Acura OBD1 Codes Retrieval
Acura vehicles 1986-95 obd1 code retrieval
There are a few different ways to retrieve the codes for "check engine light" for Acura vehicles. One method is to use a led light (sometimes 2 led lights) on the computer or controller box itself. If it has 2 led lights, the color is red and amber. The red is used for flashing the codes whereas the amber is used for adjustment. If you have only a single led light indicator, then that is used for flashing the code.
The controller box can be found by lifting the carpet of the passenger side front foot well or floorboard. You can see the led lights without removing the controller. On other models, you can find the controller under the driver or passenger front seat.
The second way to get the code is using a jumper wire on the diagnostic connector located on the kick panel at the front passenger side. You then watch the codes being flashed at the dash panel after you turn the key on. To read the code being flashed is easy. Example: Code 23 is 2 long flashes followed by 3 short flashes. A longer pause separates the next code that follows.
Here are Acura vehicles 1986-95 general codes:
Code 0 Electronic control unit (ecu)
Code 1 02 (oxygen) sensor
Code 3 and 5 map sensor
Code 4 Crank angle sensor
Code 6 Coolant temperature sensor
Code 7 Throttle angle sensor
Code 8 Crank angle sensor (TDC)
Code 9 Crank angle sensor (CLY)
Code 10 Intake air temperature sensor
Code 12 EGR system fault
Code 13 Atmospheric pressure sensor
Code 14 Electronic air control valve
Code 15 Ignition output signal
Code 16 Fuel injector fault
Code 17 Vehicle speed sensor
Code 21 Spool solenoid valve
Code 22 Valve timing oil pressure switch fault
Code 23 Knock sensor
Code 41 Oxygen sensor heater fault
Code 43 Fuel supply system

SEEMS TO HESTITATE..LIKE BAD SPARK PLUG BUT NOT ALL THE TIME WORSE WHENEVER ENGINE IS COLD 1995BCHVY LUMINA


has the electronic engine control system been tested for trouble codes? here is how you do this test, if you have a code post it back here on this thread and I will diagnose it for you. Go to the link below to see how to run a troube code test, very easy.

DTC P1361
If the PCM does not monitor IC pulses while IC mode spark advance is commanded DTC P1361 sets.
Observe the Freeze Frame/Failure Records for this DTC.
Turn OFF the ignition for 30 seconds.
Start the engine.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.
Did the DTC fail this ignition?
Is DTC P1362 also set?
--
YES - Go to Step 6
Turn OFF the ignition.
Disconnect the ICM.
Probe the IC timing control circuit at the PCM with a test lamp connected to battery voltage.
Does the test lamp illuminate?

The ignition control module (ICM) has independent power and ground circuits. The circuits between the ICM and the powertrain control module (PCM) consist of the following circuits:

• The ignition control (IC) timing signal circuit
• The IC timing control circuit
• The low-resolution engine speed signal circuit
• A low reference signal circuit
The ICM sends 3X signals to the PCM. The ICM controls the timing advance during engine cranking. The timing advance changes to PCM control after the following actions:
• The PCM receives the second 3X signal.
• The PCM applies 5 volts to the IC timing signal circuit.
• The timing advance switches to PCM control.
• If the PCM detects a short to voltage in the IC timing signal circuit DTC P1362 sets.

The transmission pressure is modified by an adaptive modifier which controls the shift execution time. This diagnostic tests the time required to accomplish the shift. If the shift takes longer than 0.65 seconds and the adaptive modifier cannot shorten this time, then a counter increases by one.
If the PCM detects a counter value of 2 during one trip, then DTC P1811 sets. DTC P1811 is a type C DTC.
Diagnostic Aids
• Ask the customer about possible overloading, exceeding the trailer towing limit, or towing in overdrive.
• Ensure that the current PCM calibration is correct for the final drive ratio.

DTC C0035-C0051
As the wheel spins, the wheel speed sensor produces an AC signal. The electronic brake control module (EBCM) uses the frequency of the AC signal to calculate the wheel speed.

P0321 Spark Reference Circuit. The spark reference signal is used by the PCM to improve ignition timing accuracy during crank and at engine speeds of up to 1,200 RPM. The spark reference circuit allows the use of ignition control mode below 400 RPM, eliminating the need to utilize module mode during start-up, and also allows the PCM to calculate true crankshaft position in 1/6 the time that use of the fuel control reference signal would permit. During normal operation, the PCM uses the spark reference signal to control ignition timing until the engine speed exceeds 1200 RPM, at which time the fuel control reference signal is used. There is no connection to the TCS.
If everything checks ok then the PCM is defective PCM.
