Question P0333 Code & observed rodent damage

Hi all,

Currently have my 2007 FJ overseas in Bahrain, and over the last 48-72 hours, some local vermin have made themselves at home in my engine and chewed through some wires. Started the car this morning, and immediately saw the CEL, ABS, VSC, and TC lights illuminated. Read the codes, and it's the P0333 Engine Knock Sensor (Bank 2) failure code, and when I lifted the bonnet, sure enough, there are rodent footprints everywhere.

I'm looking for an estimate (time-wise) to pull the intake & exhaust manifolds, drain the coolant & fuel, and basically get all the metal out of the way to assess the true damage. Labor is cheap(ish - $5-10/hr) here, and I may or may not be able to get the parts locally (Amazon is an option via FPO).

Assuming that the knock sensors are still good (they should be), how much actual wrench time should it take to pull the intake & exhaust manifolds and check & replace damaged wiring? I've seen 20-plus hours in previous threads, but if I don't actually have to replace sensors, is it less?

Thanks in advance. Just trying to get an idea on how tightly I should clench my cheeks before bringing it in. And, no, I'm not driving it at all.

Cheerio,
Dave

Slow down a bit. Remove the plastic engine cover and air cleanerhousing and inspect what has been actually been damaged. Check to see if you have enough to splice to using factory pigtails, solder and heatshrink tubing. Toyota makes pigtails that work with the factory connectors. I had rat/mice eat the wires off of three fuel injectors. You may be able to fix without draining anything. Post pictures.

Re: P0333 Code & observed rodent damage

My wife's corolla got chewed a bit - plug wires. I was able to simply put electrical tape on them to stop them from arcing to the next wire... ALWAYS try the easy/cheap fix first. This was 10 yrs ago and it's still going strong.

Always start simple. You can solder it yourself or just twist the wires together and put some electrical tape on it......I`m sure that will fix your problem

Figured I'd post my final outcome...

I pulled the plastic engine cover & air filter housing as suggested, shone a light inside, and found no noticeable damage. Had it towed to my friendly local garage, and they spent the next 4 days pulling the engine apart, replacing the wiring harness for the knock sensor (which had been chewed clean in half), and putting it all back together. 35 hours of labor later, my car's running as new.

Luckily I'm in a place where labor is cheap, so it only set me back $290.00, tow, parts, & labor included.

Re: P0333 Code & observed rodent damage

I just went through the exact same situation.
My large wire harness from the fuse box that runs around the engine bay was destroyed along with several injector wires, chewed at the connector. Fuel lines where damaged, hose for washer fluid also.
$6800 in damaged with all new Toyota parts used to repair it. Luckily was covered by insurance.

Re: P0333 Code & observed rodent damage

Can you tell me where it was chewed in half? I found a mouse in the FJC but it was running fine then two days later P0333 rough idle but I can't find any chewed wires?

Keep looking.... could be anywhere....

On my wife's corolla it was the plug wires. So thankfully it was easy to spot and remedy.
