I am having so.e issues with my 2007 suburban, its got the 5.3l motor and the check engine reads crankshaft position sensor, i recently changed it out and the code still pops up after being erased, it does take a few seconds to start, what could be the cause of it still bringing a code when i changed the sensor new? Also it is a 4wd and i need to replace the knock sensor on the left side but the front shaft exhaust mani and stability bar are in the way any good tips to get to it?

 

Welcome to the forum, its possible the wire harness may be damaged, inspect the wire harness back from the sensor, check for heat damage, pinched wires...

 

Thanks Alright ill check the wires out, didnt pay much attention to them when i replaced the sensor, but then again they didnt look out of the normal.
