i dont know jack about the difference in years...but it sounds like you would need to swap the entire engine wire harness and all electronics attached to it....

The biggest issue it going to be emissions testing. If it's a 1997 you NEED to have it be OBDII, regardless of what engine is in it. You will need to swap over the sensors if they are different and use the computer/harness out of the 1997.

I recently had some work done on my '98 jeep cherokee classic (4.0 I6)-4wd

Ignition coil, rotor, wires, plugs...and now the CEL came on and I get the code P0138. This is my downstream O2 sensor, correct?

Could the above ignition work have an impact on the new CEL problem. The place I took it has a fixed forever warranty and I would like to take it back to them if these are connected. Free is always better.

Your help is appreciated!

Unlikely that the work has anything to do with the code, unless then blew the fuse (see below).

P0138 is the high-voltage code for the downstream (post-cat) O2 sensor. More than likely, the sensor isn't working properly because the internal resistance heater isn't functioning properly. Check the fuses in the underhood PDC (Both O2 sensor heaters are fed by a single 15A fuse) to make sure they're all working, you should also take a look at the ground ring connectors mounted to a stud on the passenger side block adjacent to the oil dipstick. Finally, take a good look at the wiring harness running along the trans tunnel to the downstream O2 sensor, it's common for the harness to become damaged from contact with the driveshaft or exhaust header.

klaric06

so what I am reading/hearing is that is probably the O2 sensor but check the fuse/relay box, correct? The Jeep is sluggish at start up; would the o2 sensor cause that?

dukie564

yes it could, especially if the heater circuit isn't working (it starts to work better once warmed up)

will an electric fan make my cherokee sound like it's not a bus?

dukie564

no, it'll sound more like a jet engine if you get one that can move enough air to cool out engine properly.

Haha, well I am confused what is left and what is right hand drive! I googled it and it says UK drives on left hand, and we (US)do right hand. So... I thought I need a right hand part. I live in the US and my XJ is "regular", if you want, just like most XJs in the US, lol. I've seen a few a few that have the wheel on the other side, like UK, Japan, Australia, etc, but like two-three maximum within years...
Sorry if I sound dumb, but what part will I need?

btw, many thanks for the links and all.

You need the left hand drive part. We drive on the right side of the road, but since the steering wheel is on the driver's left of the vehicle, it's called left hand drive. It can be confusing.
It looks like they've replaced the "Poly Cog" with the "Poly Rib." I've always had good luck with Dayco belts and hoses, and last time I bought one, it was made in the USA.

yes it does
