Question about 1991 Dodge Ram 150

Maintenance Required Light

I purchased a used 1990 Dodge Ram truck from my father-in-law who had always performed his own maintenance. The Maintenance Required Light stays on and he no longer has a book that told how to reset the light.

I tried a few things that worked on other vehicles, but nothing has worked on this truck. Can you help me?

Thanks!

If you can find someone with a DRB scanner or an older Snap On scanner, you can turn the light out with the scanner.

How can i reset maintenance required light on 2007 toyota prius


Take it to your nearest Toyota service department and have the required service performed. Believe me, preventive maintenance is much cheaper than repairs that are required from part failure from a missed service.

Maintanance required light on


turn the key to activate the power but not start the ignition, do this a handfull of times. The check engine light should blink a specific number of times, this can be referenced to identify the problem, after this happens the light should turn off until you have another problem!There's a difference between the "check engine" light and the "engine maintenance required" light (aka "Emission Maintenance Reminder" or EMR light). The EMR light is strickly a reminder that emission system maintenance is due. This includes the EGR valve, PCV valve, & Oxygen sensor. It is program to light at approximately 60,000, 82,500, & 120,000 miles. Because its activated by mileage, it does not necessarily mean that something has malfuction. Unfortunately, the only way to reset it is by using a diagnostic scan tool. Of course, you could always remove the bulb.

What does the maintenance required light mean


It's a service reminder light the you're do for maintenance. Check owners manual - compare your cars' miles vs maintenance required. Light needs to be reset after service is performed.

The computer on the truck says to have maintenance performed. Checking the owners manual, it says the EGR valve needs to be replaced. Where is the EGR valve, what does it do and where do I get the part?...


Are you sure that the Owners Manual is telling you to replace your EGR Valve or is it simply telling you to check it? Does the light on the dash say "Maintenance Required"? or is your Check Engine light on? If your vehicle is equipped with "Maintenance Required" light, the vehicle usually does not need anything. You simply check the systems that are listed by the manufacturer to check, make repairs only as necessary, and reset the light. Chrysler did some goofy stuff with Maintenance Required lights back in the 80's where they recommended replacemet of a whole bunch of parts that the vehicle didn't need to have replaced. We used to just reset the light and send the vehicle back to the customer. I haven't seen one of those for a while. If your 2007 has one of these, it means Chrysler is up to some old stuff for 2007.
On the other hand, if it is the "Check Engine" light that is on, the computer needs to be scanned for fault codes and diagnosed and repaired accordingly. Also EGR valve failures are pretty rare. When the Engine Computer sets a fault code for the EGR system it usually is not caused by the EGR Valve itself. Your 2007 is OBDII compatible, which means if you are having a problem with your EGR System the Check Engine light will be on and fault codes will be stored in the Engine Computer.

The following are the common maintenance expenses after 200000 km.

1. Clutch Plate or even entire assembly recondition
2. Brake Assy maintenance
3. Check the engine performance, like speed, engine heating, etc ( Due to improper service or maintenance you may also face the problem )

Thank you.

Maintenance Required message on. Purchased


this light can come on even thought service is not actually due. if the service was performed and the light was not on at the time, sometimes you cannot reset them if they are not actually lit, or 99% of the time the technician forgets if the light was not on. stop by your shop and they can reset it for you in just a few moments, and for no charge. good luck!

Reset maintenance light


If I remember correctly, on the dash you have a select button. Hold the button down then turn the key on, until the maintenance light blinks and goes out. Turn the key off then back on and your light should be out.
