Question about 1988 Chevrolet S-10

1 Answer

EGR problem I have Saturn SL '97 and the Service Engine Light is on. I went to Auto Zone and they check the car with a coding machine. The coding said that it was the EGR so I replace the EGR, clean the system and the light still on. I went back and the machine said Insufficient flow. What it could be the problem? Thanks

Service engine light comes on with obd code of p1404, p0405. What do i check ?


Code 1404 for Saturn cars means the computer thinks the EGR is not closing. But it can also mean the computer needs to be re-programmed. There are service bulletins for some models.
Code 405 is a problem with the EGR sensor which can be causing the other code.
Generally the sensor is telling the computer the valve is not closed when the computer commands it to be closed.
It may be tough to fix if the problem is not constant.

Service engine light is on, with no error codes


Disconnect the negitive battery cable for an hour. This should clear it. Also check the oil levels. Its possible they didnt fill them to the proper levels.

I have a 97 saturn what does it mean when the service engine soon light comes on and stays on?


It means the computer has detected a problem. Take the car to auto zone and ask them to pull the codes and post the code here. The code will pin point the problem.

Service light comes on in about 30 seconds in a saturn sl2


Go to SaturnFriendsForums.com it's a great site with a WEALTH of info on saturn specific problem solving.

In the mean time have auto zone or other parts place read the codes for the service light,

MOST problems are caused by a bad water temp sensor on the right side of the engine down low ( looking at it from the front of the car ) it's called the ECTS sensor, get a BRASS one from auto zone for $8.00 it will solve a lot of problems that there may not be a code for.

Have 95 saturn sl with code 26 and 27 quad driver


well the quad driver may not be at fualt and most likely is not.

there is a fualt line that the computer uses to monitor for fualts but the thing is one line monitors four different things and the code is to get you in the general area but not to the exact fualt. so from here you need to test for failed components. that code and the quad driver monitors the a/c , evap solniod , egr solenoid and coolant fan relay. the fan relay and egr are the most common i see all the time. and with you having an isssue with that coolant light i want to say check the fan circuit.

let me know if you have more question thank you and good luck

Service Engine light staying on


A code P0442 most likely means one or more of the following has happened: a loose or improperly affixed gas cap; a non-conforming gas cap (i.e. not factory/original brand); a small leak/hole in a fuel vapor hose/tube; other small leak in EVAP system; faulty vent o-ring seal

The EGR Valve is located on top of the intake manifold. If you are standing in front of the car it would be on your right hand side. It is cylinder in shape and has wire harness that connects to the back of the engine!

High idle/low idle pattern


This issue is caused by the egr valve being stuck open, more than likely. Just remove it and clean the plunger on it. Also clean out the two ports that are in the intake. Check out saturnfans.com for more information. I hope this helps.
