Hi!!

my car is 2016 Lexus IS350F and
I recently repaired those issue from local auto repair shop when I inspected dealership with yellow engine light on :


-Spark Plugs
-Condenser
-Catalytic Converter

after pickup up my car , there is more code and loud sound from engine room and mechanic can't handle anymore how he could figure it out

my code are :


P0102 : Mass or Volume Air Flow Sensor A Circuit Low
P0113 : Intake Air Temperature Sensor 1 Circuit High Bank 1
P0345 : Camshaft Position Sensor A Circuit Bank 2


He replaced camshaft sensor but code still on and recommend me to get diagnose & inspection from dealership and need fix it.

I already spent 4k and my closest dealership is 700km away from me.

I have nightmares and I'm nervous. I need to drive a car everyday for my work. He said I need to be careful while I am driving the car and there is risk when I drive far away to get to the dealership as well.


He seems to have broken down more than what I brought my car to and I need to spend more on towing service.


My question is, could I drive 700km with those issues? or do you think I should tow my car to the dealership.

My engine sounds loud when I start the engine and calm down after 10 sec. After I hit the accelerator, sounds come again.


Please give me advice and help me..



Thank you. .



Please watch video what my car sounds like .. I feel my heart has got broken

 

Ok, so this may be cheating, and may not be relevant, but I entered the following query into ChatGPT:

”Given the following engine diagnostic codes p0345, p0113, p0102, what could cause this?”

I got the following response:
The diagnostic trouble codes (DTCs) you’ve listed suggest multiple potential issues, but there may be a common root cause. Here’s a breakdown of what each code means:

1. P0345 – Camshaft Position Sensor “A” Circuit (Bank 2)

• Indicates a problem with the camshaft position sensor circuit for bank 2.
• Possible causes:
  • Faulty camshaft position sensor
  • Damaged wiring or connector
  • Timing chain or belt issue
  • Engine control module (ECM) fault

2. P0113 – Intake Air Temperature (IAT) Sensor 1 Circuit High Input

• The sensor is reporting a much colder air temp than expected (high voltage).
• Possible causes:
  • Unplugged or faulty IAT sensor
  • Open circuit in the IAT wiring
  • Dirty or contaminated sensor

3. P0102 – Mass Air Flow (MAF) Sensor Circuit Low Input

• The MAF sensor signal is lower than expected.
• Possible causes:
  • Dirty or faulty MAF sensor
  • Intake air leak (vacuum leak)
  • Wiring/connectivity issues
  • Clogged air filter

Possible Common Causes for All Three Codes Together:

Given that all three sensors (camshaft, IAT, and MAF) are showing circuit-related issues, this may suggest a shared electrical problem, such as:

• A blown fuse or bad ground that affects multiple sensors.
• A damaged engine wiring harness (rodent damage, rubbing/chafing, corrosion).
• Faulty ECU or a poor ECU ground.
• Loose or corroded connectors at or near the sensors or ECU.

Recommended Diagnostic Steps:

1. Check fuses related to the engine and sensors.
2. Inspect the wiring harness and connectors for visible damage or corrosion.
3. Check battery voltage and ground connections.
4. Use a multimeter to test continuity and voltage at the affected sensors.
5. Clear the codes after addressing any issues and see if they return.

 

Thanks. Do you think if i drove 800km drive car to dealership, is it worth it, or should I call towing service.. ?

 

I wish I could give you a definitive answer on that. If it’s just an electrical gremlin, you’d probably be ok. But I’d hate for you to damage the car (beyond what is currently going on) based on an unprofessional opinion. If you want to avoid risk, have it towed (or preferably flat-bedded that distance) to the dealer.

 

I think you should first look in the engine compartment yourself and make sure that there aren't any unplugged connectors.
