2005 Chevrolet Silverado 1500: check engine light

Filed Dec 11, 2022 · Engine · NH

Recently replaced o2 Sensor and cleared check engine status. I failed the state emissions test because the Cat indicates inc or not ready,(catalytic converter). The procedure to clear this condition is dangerous and unreasonable. It calls for accelerating to 55MPH or higher for 2-3 minutes then decelerating to 20 MPH, not using brakes, and travel for 2 minutes then accelerating back to 55MPH, repeating this process up to 5 cycles to clear the CAT status. Given the drive speed this procedure would have to be done on a highway and could very likely cause a collision. This is very hazardous and should not be a requirement to complete vehicle inspection.

Truck has an exhaust leak at manifolds. 4 bolts have broken off of the manifold. My mechanic said this is very common with this truck and could cost up to and over $1,000.00 to fix. Check engine light is on so unless I fix it I can't go to state inspection. Also the brake lines are corroded and also need to be replaced. These are all defects not maintenance issues.

Chevy silverado and chevy suburban with same problem. Check engine light comes on. This could either mean to check engine or that the gas cap is loose. Engine was checked and so was gas cap. Nothing wrong. Servicer turned off the check engine light. Next time truck was started up the light came on again.

I had to replace the cannistor evaporation solenoid because of repeated check engine sensor. This cost me $330. The mechanic told me this is a retrofit part that chevy has come up with which tells me that chevy is fully aware of this very common problem with this truck. I know of 4 other people who have the same truck and the same problem. I want chevy to reimburse me for this repair.

I was driving to the store and when I looker at my speedometer I was doing 110mph and when I came to a stop it displayed 60mph that happened 12/31/08 at 70,000 miles. So far my problems with my 2005 silverado at 20,000 miles I had the steering wheel clump fixed by packing it with grease now the problem is back,at 60,000 miles my fuel pump failed on a road trip after I started to fill hesitation like starving for gas- cost$ 700.00, at 65,000 miles the catalytic converter was plugged up the engine light came on and would blink and would hesitate really bad when you would punch it into passing gear. It didn't cost me anything because of the emission law 70,000 or 7yrs,and it just turned over 70,000. But I still love my truck and I always drive a chevy. That fuel pump could be fixed easy if they would put a access door in the truck bed because gm fuel pumps are junk, same thing happened to my chevy astro.
