The wrench means you need to service the engine ASAP. The check engine light has a lot to do with all the pollution control devices on the vehicle. It could be the fuel filter I always recommend to my customers to change them out on a diesel every 15,000 miles . It will save a lot of headaches.

SOURCE: Check engine light and it is slow in speeding up. Please help

I had the same problem. The first thing that came up when they scanned my car was that I needed a new throttle body. Got that. That got rid of my car riding rough. Then they scanned it again for the flashing light. What came up was transmission range sensor. Costs about 45 bucks and my car has been driving like a dream for almost a couple days now :) I only got it on Wednesday but so far so good!

SOURCE: Hyundai i30 Diesel automatic won't accelerate above idle at light

DOES THE ENGINE MIL WARNING LIGHT COME ON? WITH OUT MORE INFO YOU NEED TO CHECK MOTOR ON A CODE READER FOR STORED FAULTS, CHECK ALL AIR LINES TO EMMISION CONTROL, , SOUNDS LIKE YOU HAVE GONE INTO SAFE MODE, A SPLIT OR LEAKING PIPE ON THE INTERCOOLER IS A COMON FAULT ON THESE, IF YOU SWITCH ENGINE OF AND BACK ON QUICKLY WITH MOTOR RUNNING WITH OUT STALLING MOTOR AND IT CLEARS THEN IT IS PROBERLY THE SAFE MODE CUTING IN MEANING A FAULT HAS BEEN SEEN BY PCM

Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.

Hi i got a gwm 2.8 TD not starting.check all fuses.tested injector pulse with diode test light and no pulse found.tested ecu with another gwm 2.8 and is starting with my ecu.


Not sure what a diode test light is, but I would check with a DC voltmeter for a 12 volt pulse. The pulse is very short in duration, so you might not see it. Check for spark at the spark plugs. If fuel pump is bad, you won't have fuel pressure. There are numerous reasons for an engine not starting.

Triangle with car and skid marks behind car and a triangle with wrench both dash board warning lights


{: ) These triangles you saw is for the Stabilitrak (traction control) indicators. Normally these lights should be off after the engine has started, unless you disable it by pressing the stabilitrak button. Sometimes it lights up automatically when driving under certain road conditions, and will turn off later when normal conditions resume. A wrench beside the triangle indicates a fault is detected on thge traction system and it requires servicing.
What you can try, stop the vehicle, turn ignition off for a few seconds to reset the system, and then restart the vehicle. If the lights wont go off, then tghe vehicle really needed to be checked right away.
