EGR Sensor A circuit high 6.4 ~ Limp Mode?
truck is a 08 with 96k miles,
yesterday when I was returning home, the check engine light came on and the power became sluggish, it drove smooth but took a while to get up to speed.
today I tried scanning it, and my old scanner could not link up, so I went to autozone and they scanned it, turned out to be the egr sensor a circuit high, he said it appeared twice. he cleared it, and i started driving. there was no CEL but it was still sluggish. about 15 mins later the CEL light came back on. Any idea what this code exactly means and best way to fix it? truck is 100% stock.
Only thing I can think of is the last few regens were canceled because I was almost done driving so it has not regened in a few weeks. Also, my last fill up was b5 diesel because they were out of normal diesel. Last week I also changed the batteries. Fuel filters were done a few thousand miles ago. I am not noticing any smoke.
