When I noticed that the gauge was all the way in the red, I was already parking at work. The coolant light was not on, so I figured it may be an electrical issue. I then turned the engine off and then started it up again, and the guage returned to normal/warm. In addition, I didn't smell anything, but what do you think? Im going to the shop directly after work, but I value your opinion. Moreover, my camshaft position sensor is acting up and I just received the part but I have not installed it yet. Could that be related? the error code did refer to the circuit. let me know, thanks. |
