I was running the 1145 long before the other codes appeared. My truck ran fine with the 1145 code but my gas mileage suffered somewhat. Then even more so when I had the coil issue appear and you are forced to repair the problem. Sunny,

Can a P1145 cause a P1320 to show up? Just wondering if a really have a possible bad coil or if the bad sensor is causing the misfire. Thanks Hi,

The CEL or SES light sometimes needs to be cleared. As illustrated by both of your experiences, the code can clear on it's own or need some help from a code reader. It is preferable to let the code clear on it's own because a manually cleared code can sometimes prevent the vehicle from passing a state inspection. If you are forced to clear it as Mike did, then you have no other choice. The ECM that controls all this is not the most powerful or reliable computer known to man. It has it's flaws and limitations. @Mike and Eric,

Just purchased an 02' Pathfinder and within a day, the CEL came on. The code was P1140; so I found your write-up and replaced both sensors. However, the CEL was still on after many days of driving. A local mechanic scanned it again and said there are no codes stored and cleared for me. CEL is reset. Thanks again!!! Thank you for the terrific write-up.

I had an 1145 code on my 01 Pathfinder. Your detailed instructions made it easy for me to replace this $60 part in about 30 minutes. The part was easy to see but somewhat harder to wiggle out due to all the wiring around it. Unplugging some of the wiring directly above the part made replacing much easier. My SES went off after the repair and my gas mileage is up again. Thank you! Great info here Jen! I had an 1145 code on my 01 Pathfinder.

The computer in these vehicles is very rudimentary. Codes can 'stick'. After far as the solenoids go, I updated the post with a picture from a repair manual. The sensors are pretty easy to change out and usually go in pairs. If one fails, the other is not too far behind. @John

Was getting the passenger side code thrown so I swapped the sensors. Couple hundred miles later, the code stayed put and didn't follow the "bad" sensor. So the next step would be that solenoid. Where on/in the engine should I be looking for this thing at? Thanks for your help! Hi Jen, tried your trick. Was getting the passenger side code thrown so I swapped the sensors.

The sensor is made by Standard Motor Products, part number PC458. I found the part on amazon.com for $58 (free shipping). P1140 (passenger side) and P1145 (driver side on top) are same part number.

After an oil change, the "check engine" light turned on and im getting the P0022 code. The code description says its "A" camshaft sensor solenoid - advanced degree Bank 2. Now I tested the harness that goes into the sensor and everything is ok. Removed and cleaned the sensor, cleared the codes on the ECU, but after a few minutes of driving it comes back on. Im getting really poor gas mileage on my pathfinder right now. A full gas tank only lasted 160 miles and it was back at empty again. I removed the 2 camshaft sensors but they are not the same, the left one has 2 wires and the right one has 3 wires, so I cant exchange them to do the test. Do you know where the camshaft solenoid is located? Is it visible or do I have to take out the valve cover to see it? Any suggestions? Thanks for your time!
