Question about 1992 Oldsmobile 88

1 Answer

Throttle Problems I own a 1992 oldsmobile 88. I have changed the TPS sensor about a year ago due to some Throttle problems but not they are back. Is it possible that the TPS went bad again. Or is there something else I could possible try. The throttle body seems to be in good shape has a strong spring and I inspected the gas pedal to see if anything was catching so far I have found nothing. Any help would be appreciated!

Go to an autoparts store like autozone or advance (also check out their websites). Some stores can test the throttle position sensor so that you will know if it is the problem or not. No sense guessing or replacing something that doesn't need replacing. Just because the TPS is only a year old doesn't mean it can't be faulty. Hope this helps and best wishes.

92 oldsmobile 88 royale check engine code 55


Check the Mass Air Flow Sensor, you can get a can of cleaner specific for cleaning them for a couple bucks at the parts store. I'd just get 1 and clean the sensor see if that works. The MAF sensor is either in the throttle body itself (bolted on from the outside or in the air line between the filter and throttle body. That could be the whole problem right there. Good luck.

P0122 error code on a 1999 oldsmobile 88


P0122 Code - Throttle Position Sensor/Switch A Circuit Low Input
A P0122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V).

Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage.

Symptoms may include:
Rough or low idle
Stalling
Surging
No/little acceleration
other symptoms may also be present

Causes: A code P0122 may mean that one or more of the following has happened:
TPS not mounted securely
TPS circuit short to ground or another wire
Faulty TPS
Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
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.


Test it and keep us updated.

1992 K1500, code 22, clicking noise from throttle body, will not accelerate properly, changed TPS with no change


OBD Code 22 - Throttle Position Sensor Error (Signal Low)
The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve. The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

Symptoms:
* Extended cranking, possible no-start condition
* Lack of power
* Erratic transmission operation

Common Problems:
* A failed Throttle Position Sensor (TPS) would be the most common causes for code 22
* Testing the TPS circuit would involve checking voltage and ground from the ECM-5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM would involve monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is "jumpered" to low when the jumper is removed.


Keep us updated.

I have a 1992 olds 88 runs fine when its cold but when it gets warm it wants to run bad back firing missing ben working on it for weeks replaced mass airflow tps and air sensors also notice that radiator...


replace coolant temperature sensor and go from there!! here are a few causes for engine back fires--common causes are==lean misfire due to low fuel pressure or restricted injectors. breakdown of secondary including internal ignition, coil arching and a dead spot in throttle position sensor. it is hard to say with out being there!! but my first guess would be to check out tps first. then go from there. have a good day!!

Where is the engine idle screw for a 1990 3.8 liter v-6 in an oldsmobile delta 88 ?


Umm there is no engine idle screw on those type of vehicles.. If you are having problems with your idle then check the TPS(Throttle Position Sensor)sensor which is usually located on top of the intake..

Bucking engine


Check the fuel pressure,also change the fuel filter.check the crankshaft sensor,or replace.It sounds more like the tps sensor(throttle position sensor).It is mounted in line with the throttle axle,on the throttle horn.Of course .with out being there and checking I am just guessing.But map sensor or mass air flow sensor could also cause this.Have you checked the air filter?This will cause the problem,if it is stopped up restricting air flow to engine and mass air flow.,map sensor,and vacuums needed to run the car.If I can help,let me know.

Try turning the key to the on postion-not crank, just to he postion right before cranking. leave it in that postion for 15 min, Do this three and after the third time go ahead an try to start it. Hopefully this will reset your security for you.

Hi there I have a 1988 delta 88 the problem is that when I start it up and drive it wants to stall out but when the temperature rises it runs alot better not to sure if this is the problem I have replaced...


Could be several issues that are common with GM cars :
  1. Bad MAP sensor
  2. Bad TPS (Throttle Position Sensor)
These are the most common areas that would cause the problem you have.
