I replaced the rear cat w an aftermarket and a few thousand miles later the ck eng lite came on. I was told by sum1 from toyota dealership that the aftermarket cat is less restrictive or the honeycomb has a different design causing the ck engine lite. I just noticed 2day an oil burning smell and i was approx 1 qt low in oil. I ck the level a few times to confirm. Any recommendations on the problem...I know of a sludge problem on these camry engines and recieved a letter from them. I'm jus trying 2 maintain this car as best as possible having 140k+.

#87 of 150 Engine-Check Light On: Overheat? by frenchhoffman

My Camry's engine-check light was lit while I was driving to work today, and shortly after that, heat wave came out of the air conditioning chamber while the AC is turned off:
 
What does this mean?
 
It is a 2004 made Toyota Camry LE with 86k miles on it.
 
Thanks in advance.

What did your temperature gauge read? Did you check under the hood afterward to see how much coolant you have in the see-through reserve tank?
 
Caution: Do not remove the radiator cap (on the radiator itself, not the reserve tank) until the engine is cold.

The temperature gauge stayed in the middle. No sign of overheating on the panel... The coolant level is between MAX and MIN...
 
Having reviewed the Toyota Camry owner's manual, I realized that a loose fuel tank cap could also cause the light to go up (but it should go off after a few trips if there is nothing else going on).
 
So I checked my car's fuel tank cap and found that it couldn't be securely tightened! That is, after I turned it clockwise and heard a click--supposedly the cap should have been tightened--the cap was still loose (i.e., it can be easily pulled off the nozzle, without turning it counterclockwise)... I guess this fuel tank cap is no longer usable and needs to be replaced...
 
But... Why is heat coming out of the air conditioner chamber? Where does it come from? Is there a connection between the heat and the loose fuel tank cap? Is the heat or the loose fuel tank cap keeping the engine check light on? Or both?
 
I guess I should stop guessing and get some help...

I found the Technical Service Bulletin It is EG024-04.

Models:
'02 - '04 Camry (2AZ-FE) (Non PZEV)

Thanks, with your information, I found I have the TSB itself, which I originally obtained from the Bedford County Library (Indiana) online. (They have since removed these TSBs from public access.)
 
TSB EG024-04, July 1, 2004
 
Title:
M.I.L. “ON” DTC P0420 [Note: M.I.L. = Malfunction Indicator Lamp = Check engne light]
Models:
‘02 – ‘04 Camry (2AZ-FE) (Non PZEV)
 
Some 2002 - 2004 model year Camry vehicles equipped with the 4 cylinder (2AZ--FE) engine may exhibit a M.I.L. “ON” condition with Diagnostic Trouble Code (DTC) P0420 (Catalyst System Efficiency Below Threshold, Bank 1) in the Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM). The ECM (PCM) logic has been modified and a redesigned catalyst has been provided.
 
MODEL Camry (2AZ-FE)
PLANT / PRODUCTION CHANGE EFFECTIVE VIN
TMM Kentucky Line 1: 4T1BE3#K#4U323000
TMM Kentucky Line 2: 4T1BE3#K#4U869000
Tsutsumi Japan: JTDBE3#K#40283686
 
The repair procedure in this TSB is similar to TSB No. EG013-04 “Excessive Sulfur Dioxide Odor.” The recalibration of the ECM (PCM) should only be performed ONCE.
 
Procedures:
Recalibrate Engine ECM (PCM)
R & R Catalytic Converter Assembly
 
All 2002 - 2004 model year vehicles equipped with manual transmissions require replacement of the catalytic converter assembly only.
 
Applicable Warranty*:
This repair is covered under the Toyota Specified Major Emission Control Component Warranty. This warranty is in effect for 96 months or 80,000 miles, whichever occurs first, from the vehicle’s in-service date.
 
* Warranty application is limited to correction of a problem based upon a customer’s specific complaint.
 
This isn't the complete TSB, but being in pdf form, I copied the most important portions for people to move forward with any complaints.
 
Hope this helps!

I own a 2003 Camry with 135,000 miles and I just had the catalytic converter placed by the Toyota dealership - not aftermarket. My car seems really sluggish now -- not much power at all. I turned on the a/c (1,500miles after the replacement of the cc) and I felt like I was driving a dump truck. Is this typical? Are there any symptoms I should look for? The rpms are normal -- just no power.. Any ideas???

I just had it done on a 2002 Camry 4 cyl over 150,000 miles and it is still as snappy as ever. Did they reprogram the ECM after the replacement? It must be done and then you have to retrain the computer to how you drive. It's a bummer my 2002 Camry has more power and speed than my 2008 Tacoma and better gas mileage, 30mpg. I wish they would have used the same engine in my 2008.

#94 of 150 2003 Camry replace engine control module? by cogi320

May 02, 2010 (8:25 am)

I have a 2003 Toyota Camry (original owner) 116K miles. The engine light came on and stays on No mechanical problems. Took it to dealer, they say i need to have engine control module replaced; code P0607. Cost would be over $1,000. Does this really need to be replaced? Could I have it done cheaper somewhere else? I need my car for work, and certainly don't want to buy a new car at this time.
Thank You.

By all means, get a second opinion from an independent reputable shop. Ask for recommendations from friends, relatives, or co-workers.
