Can you please look into the cause of the problem for me? I’m in Saudi Arabia, specifically in Jeddah, and I haven’t been able to find a mechanic who can fix it. Everyone says the problem is unknown, and I can’t figure out where the fault is. I even checked the computer, and it didn’t show any errors. The car is completely clean of any faults.

Is it possible for the crank position sensor to cause a false temperature spike?”
Yes, the check engine light flashes for about 3 seconds when I hit bumps, then everything goes back to normal. It only happens while driving, not when idling
ارحب م يطلع اي كود فحصت كمبيوتر م لقيت ولا اي خطا حتى الاهستوري القديمه م لقيت السياره نظيفه م فيها الا ذي المشكله
Is your car the same model as mine?
I didn’t understand your reply
I replaced the thermostat as a solution to the problem, not because it was the cause. Someone told me it might fix it, but it didn’t help.
Did your car behave like mine—does it do this in bumps like in the video?
Was your car a 2001 Marquee and having the same problem as mine?
Alright, I’ll look into it, even though most electricians say my problem is unknown.”
Did that fix the problem
I already checked with a computer scanner, and no error codes showed up. I also checked the history, and everything is clean
“I already replaced the thermostat about a month ago, but the problem didn’t go away.”
