Ls430 With Many Codes P1354 And So On...

[KentIS300]

Hello guys,

I thought it would be best to start a thread on here instead of in the generic section.

Here are the codes the car had when I bought it

P0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) /21
P0155 - O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1) or Oxygen Sensor Heater Current is Less than 0.25 amp, or Exceeds 2 amps or Voltage Drop for the Heater Exceeds 5 Volts (Cam.)
P1351 - VVT (Variable Valve Timing) Sensor/Camshaft Position Sensor Circuit Range/Performance Problem (Bank 2)
P1354 - VVT (Variable Valve Timing) System Malfunction (Bank 2)
P1651 - VSV For ACIS Circuit Malfunction
P1663 - OCV (Oil Control Valve) Circuit Malfunction (Bank 2)

I cleaned the MAF sensor and then I took the car out for a run, then I got new codes

P0300 -- Random/Multiple Cylinder Misfire Detected or Misfiring Of Multiple Cylinders During Same 200-1000 Engine Revolutions

P0302 -- Cylinder 2 Misfire Detected

P0304 -- Cylinder 4 Misfire Detected

P0306 -- Cylinder 6 Misfire Detected

P0308 -- Cylinder 8 Misfire Detected

P1354 -- VVT (Variable Valve Timing) System Malfunction (Bank 2)

P1651 -- VSV For ACIS Circuit Malfunction

I understand the P1651 is not relevant to misfires and check VSC warnings I am getting.

Do you suggest if I clean and if no joy then replace the OCV on bank 2 (P1354) would solve my problems?

I have no idea when the cambelt was changed I cannot find any receipts etc... or when I contacted the dealers in the service book did not have an idea. Problem is the 100k service was done in 2007 and that dealer does not have records older than 3yo.... so even if he done it, he would not have known.

Cheers in advance guys.

I thought at one time Lexus main dealer servicing was recorded and kept at the Centre and available for all main dealers to obtain.

The 100k service was done by a BMW specialist... ?

But with Lexus it is not the case apparently, the RX400h we had shortly ... had it serviced to Lexus Canterbury prior to giving it to the friend who bought it.

I called Lexus Twickenham earlier in the week to book her in for the annual service as this is closest to her, and Lexus Twickenham said they are not able to see the services that happened on other dealers and best to bring the service book and invoices with her.

I remember when I was in Lexus Canterbury it was a similar situation.

However I think Toyota is linked...

strange lol.

Now a strange thing just got back with the car, I was out driving in traffic.

Before I set off, I cleared the codes.

Half way at my journey I looked at the codes and it was

P1354 -- VVT (Variable Valve Timing) System Malfunction (Bank 2)

P1651 -- VSV For ACIS Circuit Malfunction

Then once I finished my journey before I switch off the car I thought I would do one more scan and I had the following codes

P0135 -- O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) /21

P0155 -- O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1) or Oxygen Sensor Heater Current is Less than 0.25 amp, or Exceeds 2 amps or Voltage Drop for the Heater Exceeds 5 Volts (Cam.)

P1354 -- VVT (Variable Valve Timing) System Malfunction (Bank 2)

With outstanding code

P1351 -- VVT (Variable Valve Timing) Sensor/Camshaft Position Sensor Circuit Range/Performance Problem (Bank 2)

I swear the car is haunted! lol

Where shall I start looking tomorrow? :(

[KentIS300]

I have replaced the OCV valve on the driver side and has fixed all the misfiring.

Now I have only the VSV code and the O2 codes :)

At least the good news are that the car has passed it's MOT today. The only advisory being the EML light.

Really pleased
