Check your battery voltage and grounds.
Consider buying a basic bluetooth scanner preferably one than can provide live data.
I've read where members on the forum thrown those codes with a inter-mitten O2 sensor or a sticky shift solenoid.
Basically there's not enough symptoms or data to chase.

Thanks. Battery voltage and ground is fine, I just replaced the battery to a new one a month back. Old battery was leaking and had carbon around the terminals. Could that be the reason for the code, I cleaned everything with the new battery. How to identify if I have an intermittent O2 sensor of if shift solenoid if sticky?

 

Really need access to a scanner, preferably with Live Data Capabilities so if an issue is inter-mitten you can see under what conditions it happened.

 

Thanks for help. I have ordered a blue driver scanner. Will scan and share the live data. Car is not even doing 500KM in a full tank that’s ridiculously low.

 

Without the engine light illuminating, I am struggling to understand how your fuel consumption rate could be so high.

May be that it's a combination of driving conditions, especially with short trips having to run on a cold engine.

Is it hilly where you are now driving?

A bad thermostat or temperature sensor are things that could increase fuel use rate considerably without tripping the engine light (fuel mixture richness and engine rpm's would both be increased by the powertrain computer).

 

Hi,
Update is that I have done a live scan and it seems all the sensors are working including O2 and temperature sensor. Still the fuel consumption is really high it’s giving my 380KM on a full tank of 50 litres. Can’t make out what could be the reason. Mechanic is saying that may be the gear shifting is the problem but he is not sure. Any ideas how to pin point the issue?

 

A thermostat that doesn't close reliably will also affect the shifting behavior, furthering it's bad effect on fuel consumption.

Does your temperature gauge read in the middle of it's range within two minutes of driving?

 

I had code p1604 on my 2012 Camry. The car worked perfectly. I would clear the code, but it kept coming back. The first thing I tried was to clean the throttle body. That fixed it. After cleaning the throttle body, the code never came back. These Toyotas truly are solid machines.
