98 C1500 Silverado ''service engine soon'' light


My truck just turned over 60k miles. When it hit 60,723 (quite a random number to be triggered by the odometer) the light came on.

I did rinse the engine off with the water hose earlier that day.

Truck runs great, has had water pump, timing belt and alternator.

Any ideas?

    Great! I was wondering if the AutoZone or Advanced Auto would scan it for me. I'll cruise by tomorrow and get it checked. I'll let you know what I find out.

The service engine soon lite comes on due to an input sensor to your vehicles computer that has gone out of its parameters. this lite does not come on due to mileage. the computer needs to be scanned for code #'s in order to diagnose correctly. autozone will scan codes for free. if you get me the code #, ill try to assist further, otherwise you may want to see your local garage.

Why would my service engine soon light be on

  • Hi, I can help.
  • The service Engine Light Soon light means it's time for an oil change,

  • You can turn this light off real quick by following these steps.
  1. Turn the key to ACC.
  2. Press the gas pedal down all the was three times in fairly rapid succession.
  3. The service engine soon light will begin to blink and then disappear.
  4. Turn the key to off.
  5. now start your truck.
  6. The light will now be off.
  • This should be done after every oil change.
  • All the light means is that the PCM has indicated that you have driven the required miles for an oil change. A reminder light if you will.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Regards, Tony

There are literally many malfunctions that can turn that light on. You probably need someone with a code reader to pull the codes and go from there.

Service Engine Soon Light is on Car has 120,000 miles

Disconnect the battery, wait 5 minutes, then re-connect it. If that does not work, take it to the dealer. You may not have a problem other than the computer says it is time to turn it on. You may have noticed the same problem about 50-60K miles ago.
