ECU codes. Now What.

Ok as of late, my zed has been going of about 200k's per tank, and with a recent overhaul (still awsome thx PZP) i also had the o2's replaced (GB from the fourm) and now after knowing 0 about how to be mechanical i set off to do a fearful ECU check, and well i did it... yay for me

Error Code - 33 (O2 Sensor (left side) + 53 (O2 Sensor (right side)

how or who is the best way to go about fixing this.. .ie. a mechanic a, car electrician ect.... thanks

 

Buy the o2 sensors from Caz or another Local Z reseller and put them in yourself.

 

maybe your o2's died? One of Sandeeps PZP o2's packed it in recently. I'm also running them and so far so good, only done about 1200 k's on them though. Buy some new ones and see how they go. Are they plugged in? (stupid question i know but maybe the plugs weren't pushed in tightly

 

Ok so is simply a case of needing new o2 sensors... no prob thanks

 

If you recently had the O2s replaced, they should still be good, they last along time normally.

Normally if you receive an error code, this will not mean the sensor is stuffed, but an error in the circuitry, example, voltage out of spec, short circuit, open circuit, resistance out of range etc depending on the sensor in question.

You may need the wining loom or connectors inspecting that runs between your O2s and the ECU.

 

First thing is to is

Disconnect both O2's. That will get your economy back reasonably good again until they're fixed. The car will run fine without the O2's connected.

Now to fix it. Firstly make sure the connectors are not built up with corrosion and blocking signal, and do a visual check for cracked/broken wires. If all looks good you may have to try a continuity test from the ecu to check they're connected right through to the sensors.

 

haha teamwork Ben

 

ah ok thanks pex and ben, giving me more to think about as i said, i have slim to nil knowledge on the zed, so might just be for the best if i take it to an auto-electrician and tell/ask him to do all the checks you just mentioned. i mean, i dont see that being to costly of a job.

 

when you go to your auto electrician

..take a print of this with you. The guy won't have the ConZult tool required for test C, but he should be able to do the continuity tests A, B, D and E easily enough. P128 describes the connectors and P129 describes the tests.
