Would greatly appreciate if you could give me the location of the crankshaft position sensor on a 2003 nissan altima 4 cylinder 2.5 engine and a guide on how to replace it.
The engine code is QR25DE.
Crankshaft position sensor is located at the gearbox side of the engine, at the back, towards the firewall. when you take your intake hose (before MAF), you can see it.
Check the cable for damage.
