Obd11 Fault Code

[B15RUP]

Hi All, engine management light came up the the other day so I went to a friends garage and read the code via the OBD11. The fault code that has come up is P1346 Any ideas on what it could be????

I am guessing it's the Exhaust O2 sensors, but thatis a guess. Stav will confirm later.

EDIT *****

Second gues would be VVT sensor camshaft position sensor circuit range/performance (bank 1).

BTW how is the car running matey ? All finished & mapped ?

P1346- VVT sensor camshaft position sensor circuit range/performance (bank 1).

Have you had the timing belt changed recently? If so, the timing could be out, or the timing belt maybe loose/worn and it may have jumped one tooth.

Had the same problem with I changed the timing belt, I knocked the timing out when changing the belt. My car ran ok, but like you I had the engine management light on. Luckly, I didn't cause any damage to my engine, just re-set the timing and re-fitted the belt.

Thanks for the replies guys hopefully Stav will confirm Kams and Wozza's diagnosis and I will take it from there. Wozza apart from this car is good, I have posted in the supercharging/turbo forum for a little update.

Stav, do you have a list of what the actual fault codes mean? if so where can I obtain it.

I have told you what the problem is!!! I checked the fault code on my tech. CD and that is what the P1346 fault code is, basically, you have a problem with your timing/timing belt or your timing (crankshaft/camshaft) sensors have failed.

Stav will probably come back with the same answer.

I told you too after a little cheating

Calm down calm down! :D I done some google work and yes Kam you are right, just wanted a second opinion which I got from googling. :winky:

LEXUS Variable Valve Timing/CMP Sensor Range/Performance

LEXUS VVT Sensor Circuit Range/Performance Problem (Bank 1)

Yep i agree with the other two.

Right, belt has been checked and it is ok... I did have the car de-catted too but surely this would have brought up a different fault code relating the o2 as I didn't allow for an o2 simulator.

[DJ Wozza]

De-catted totally or just the pre cats taken out ?

pre cats in, but the main one under the car is out.

[DJ Wozza]

aaaah the exact opposite to mine.

I am confident mine will go through an M.O.T. Test with the pre-cats removed (after warming the engine thoroughly first).

I don't know what effect it will have with this mod on your car.

However I'm sure someone will be along soon with the right info.

[sparkystav]

Taking the main Cat out without fitting an O2 sensor will throw up a CEL light, but it'd be a different code so not sure.

UMMMMMMMMMMMMMMMMMM, I will investigate.... Anybody out there with any IMO?
