P0606 & p0157 - Toyota Nation Forum : Toyota Car and Truck Forums

Hey All,
2 weeks ago a check engine light came on with P0351-Ignition Coil "A" Primary/Secondary Circuit Malfunction, took the car to Toyota dealer and replaced ignition coil for cylinder No1. I drove the car for about 10K and check engine light came on again with P0606-PCM Processor Fault. For the past week I was monitoring the DTC's using INNOVA- CanOBD2 Code Reader 3030 (ordered ODB2 USB tool to check live data on a laptop, on it's way...). I had P0606 on all the time, about everyday. For 3 times I had P0157-O2 Sensor Circuit Low Voltage (Bank #2 Sensor #2) on.
What’s the link between the two DTC’s? Why not P0157 alone? Or P0606 alone?
Please advice what is the procedure to diagnose this?
Thanks in advance

before 2 weeks ago, when everything was normal, where there any service or changes being done on the vehicle?

Bigmama · 09-27-2010, 10:18 AM

NOP, nothing was done on the car.

If you don't know anything about cars, take it to Toyota.

If you want to read about the DTCs, Open your Factory Service Manual.

You leave out the facts..........what car, what year, what engine.

I know about cars Mister njerald, I have been reading for almost a week… did not find anything convincing. It’s why I am asking!!!! Toyota dealer said change the O2 sensor ( O2 = 260$ + 100$ labor + taxes) and will see after what happened .....

I don't want to be harsh but all the info u asked.. The response is in bleu in my signature.
What car Toyota Camry XLE, what year 07, what engine V6 2GR-FE
Thanks

Toyota got some steep prices. How many miles on your car?

Bigmama · 09-30-2010, 06:18 AM

141k Km

Bigmama,
I am going to send you some information in a PM shortly. It may or may not help you, but it at least could be a start.

Bigmama · 10-03-2010, 02:45 PM

Thank you TOYOTAPARTSMAN for the links, I was sick these days (flu and cold). Will have a look & we let you know results.

**TOYOPARTSMAN** · 10-04-2010, 05:54 AM

My pleasure, hope they help and I certainly hope you are feeling better as well.

This is an interesting problem. I could learn from your tips. Would you care to share with us.
Thanks

There is some information that I cannot share publicly, forum rules, etc. But what exactly are you looking for? Is it the same stuff I sent bigmama?
