I have a catalytic monitor incomplete and it won't pass the smog check there are no trouble codes it is a toyota camry le 1997

What part failed? Is it Calif? If so it will be specific. What would be great is if you can scan the test results and post them. NoX, CO, hydrocarbons etc....?

Ya California catalyst monitor and evap not ready

Catalyst not ready and evap not ready

Sounds like all of the "monitors" in the computer have not run to completion. Try driving the vehicle around for a few days and if the CEL does NOT come on ...take it for that Smog Test. If the light DOES come back on...you need a diagnosis and repair of a emission control device.

That above is a good point. Like a heated 02 sensor is not heating. Now EVAP not ready...not ready for what? that I don't get... unless it means it's not getting a signal..not a fault just no indication either way. But just like Lastchancegarage says.... it takes a while. Disconnect battery for about 10 minutes, and drive for as much as possible, the ECU will either re-learn or go to factory default. When I bought a new battery for my Corolla it ran like crap for about 5 miles, then purrs like it does now. But sometimes it takes longer. Much longer. Did the smog guy get that from an OBDII scan? If so exactly whet codes?

I read your question again..sorry..I see no codes there.

I put that separate to make it easy to link. You gotta see THAT ONE above it shows special specific drive patterns...warm up..miles to drive..idle...drive again..idle...IMPORTANT and may be the key to the whole thing

Preconditions The monitor will not run unless: MIL is OFF. ECT (Coolant Temp) is 176 F (80 C) or greater. IAT (Intake Air) is 14 F (–10 C) or greater

Your smog shop may not know what they are doing...if they don't follow those -- from Toyota -- to a tee

http://www.justanswer.com/toyota/5c4es-toyota-camry-can-t-evap-catalyst-monitors-reset.html ----- What you are wanting to accomplish is not to have the monitors reset but rather you want the Evap and Catalyst monitors to 'Run' and give a judgment as to whether they pass or fail. This can be a tricky process but the instructions are laid out in the Toyota Repair manual on pages 05-20 for the 4 cylinder 2AZ engine and on page 05-475 for the 6cylinder 1MZ/3MZ engine. What the Technician needs to do is drive the vehicle in the prescribed pattern laid out in the manual and the computer will then run the monitor and render judgment. ****!!*** If they do not perform the drive cycle just as the repair manual lays out, the computer will not run the monitor and will not render a judgment.

Gas tank must be between ½ and ¾ full. NO more No less

The monitor will not run because the difference between ECT (Coolant Temp) and IAT (Intake Air) is greater than 13 F (7 C

Thank you I will try this and let you know

Just run your car till the the obd monitor ready mine toyota camry 2000 4cyl it take 450 mile befoe the monitor become ready

I have a 2004 Sienna van with the same problem - Catalyst and Evap System monitors are not resetting and mechanic cannot determine the cause & won't pass inspection. I have an OBDII unit and run Car Doctor which tells me the same info as mechanic - 2 monitors "N/A". I've driven 600+ miles with still no cleared monitors and the mechanic drove his "drive cycle" as well with no luck. I'm going to try one more time before donating the car - will hate to give it up but have no choice.

Essay steeps . 1 clear all cod's with a odb . 2 star a fresh drive the morning is perfect then star your car don't drive for the first 10 min's 3 don't use a/c or Heather 3. Look for a no traffic road 4 drive your car until tracking 65 mph then decrease de speed till you reach 5 MPH without using the breaks. This well read at least 7 monitors , enough for your car to be ready. Best of luck.

I'm having the same problem with my Toyota Camry 2001 when I went to get it smogged the inspector said it rejected the smog test because the Cadillac, oxy, and evap sensors are not set. I had just replaced the battery becuse it had been sitting for the last 90 days. the guy at the smog shop told me orignaly i needed to drive my car 60+ miles an it would all set an then i could run the smog test. so I did that an came back, one of the sensors was set but the others still hadn't this time he said I just need to keep driving it. after I questioned him on what the issue was a what ways there are to fix it, just drive it can't be the only option, so he tells me to google the process to set the sensors a " cycle " the car needed to go through then the sensors would set. the steps that I found on google are kind of ridiculous starting off start the car an let idle for 10 mins then accelerate to between 50- 60 mph for 10 then without pressing the break coast down to 10mph then accelerate back to between 50-60mgh then again without pressing on the break coast to a stop and let idle for 10mins. then it said to repeat as many times as possible 2-8 times. idk where i would be able to complete these steps in my city las vegas NV it's just crazy this is the only way. so I thought to put the car on a lift/jack stands and trying to it that way but I don't have the jacks an I'm not even sure if that's safe. I'm going to try to find a spot to do it tomorrow hopefully it will get done an ill be able to get the car smogged a then registered it would really suck if it was unable and don't know what I'll do with the car.

You need to to do a complete driving cycle. google the OBD IIHome page sponsored by AutoTap to do the OBD II Driving Cycle. It has 8 steps to come the driving cycle. for catalyst being incomplete it may takes up to 5 complete driving cycle. ir works for me several times for my Hondas and Toyotas. evertime you change battery this points will be not ready on OBD DIAGNOSTIC READINGS AND WILL NOT PASS SMOG. not that your car is bad just need to reset.
