1997 mitsubishi montero sport: check engine light..accelerating

This answer was rated:

I recently got a check engine light and quickly realized that the vehicle starts, from a stop, in second gear and must be manually shifted to low, also does not downshift to first when climbing or accelerating. 1997 mitsubishi montero sport. Whatchu got?

Hi,

 

The check engine light only comes on when the on-board computer detects a fault in engine driveability or performance, emissions system, or transmission. There are literally hundreds of possible causes ranging from a vacuum leak, engine misfire, faulty sensor or solenoid, faulty control module, open short in wiring harness, internal transmission problem,etc.

 

 

 

Without knowing the exact fault codes stored in the computer it is impossible to tell you exactly what needs to be fixed. Based upon your description of the symptoms it could be a transmission shift solenoid, gear ratio error, tp sensor, open/short in wiring

 

 

Here is method to retreive fault codes yourself without a scanner:

The codes will be 2 digits - example: 2 long flashes, pause, 2 short flashes would be code 22.

 

 

Record the codes and let me know what they are and we can go from there

Where do I find the 'diagnostic trouble code I.D.? answer that and I'll accept.

Hi,

 

Sorry, below are transmission trouble code ids:

If there are no fault codes present, then it will need to go on a diagnostic scanner for testing

That's some pretty technical info, but I'll see if it helps. I'm no dummy with vehicles so I should be able to figure it out. Thanx for your promptness. Can you recomend a good manual for my rig?

Hi,

 

Best manuals are actually online. Either Alldata or Mitchell on Demand. Get a month's subscription for your year, make, model, and engine size for around $25, then download it to your computer. Alldata and Mitchell are what most shops use. Much better than Chilton or Haynes.

 

alldata.com or mitchellondemand.com

 

I personally use Mitchell on Demand- I prefer their wiring diagrams to Alldata's.
