2006 Nissan Altima Slipping/Jerking while at a constant speed
2006 Nissan Altima 4 cyl., 78,000 mi. My car has felt like it slipped/jerked while driving at a constant speed. It has only done it a few times in the last couple weeks. The last time it did it I had my cruise set to 65 mph and my service engine light turned on immediately after the slip. Any thoughts?

Have it scanned for trouble codes, record ALL code NUMBERS, post those NUMBERS here for review, and have the computer cleared. The problem could be in the engine, transmission, or electrical system. Scanning the computer should narrow things down quite a bit saving a lot of time and money guessing.

Thank you. I took it to AutoZone and they ran the diagnostic test on it. It came back as the speed sensor and crankshaft position sensor. Relatively cheap parts, but tough to get too. I'm just glad it's not the transmission.

Thanks again.

You didn't record and post the code NUMBERS as I asked you to.

Your diagnostic test at Auto Zone gave you some codes that were set by improper readings from the Speed Sensor and Crankshaft Sensor. That doesn't mean that anything is wrong with either one.

Example: My brother got a Right Front Wheel Speed Sensor code. I told him that I would check it out for him on the weekend and IF it was the speed sensor he would have to buy the whole Wheel Bearing. By the weekend he had already spent over a hundred bucks on the bearing plus a couple of hours changing it. He cleared the code, went for a test drive, and as soon as he hit 5mph the code returned and his ABS light was on. He was quite upset. When I got there we found & fixed the broken wire for a couple of bucks and the system works fine now.

A code means that the computer isn't getting information from a sensor in the range that it expects. It sets a code telling you what sensor isn't sending the proper information. It doesn't necessarily mean that there is anything wrong with the sensor. So you may or may not need those parts? Especially when 2 codes set. It is like the gas gauge being on "E" and the red "Low Fuel" light being on. You don't change the gauge and light. You put gas in the tank.

Please let us know what fixes it.
