Got back from Europe last week and check engine light came on. Never had a CEL before then.

Scanned it today, got ALL of these codes:

p0405 p0135 p0140 p0153 p0155 p0160 p0412 p0418


What the hell?


P0135 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 1

· P0405 - Exhaust Gas Recirculation (EGR) Position Sensor Circuit Low Voltage

· P0418 - Secondary Air Injection (AIR) Pump Relay Control Circuit Bank 1

· P0412 - Secondary Air Injection (AIR) Solenoid Relay Control Circuit Bank 1

· P0160 - Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 2 Sensor 2

· P0155 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 2 Sensor 1 · P0153 - Heated Oxygen Sensor (HO2S) Slow Response Bank 2 Sensor 1

· P0153 - Heated Oxygen Sensor (HO2S) Slow Response Bank 2 Sensor 1



I'd like to mention that my car has no cats, and I believe ERG is deleted. Why would one O2 sensor trigger all these codes?

Check your fuses? I think The egr and transmission are powered from the same fuse. I think o2s come from that fuse too. Ive seen a o2 melt and ground on a header, blow the fuse and make everything go nuts...

The P0160 and P0405 are throwing because you have deleted the cats and egr. They will always show up until tuned out. The Bank 1 and Bank 2 sensor 1 codes are your front O2s which need to be replaced. The rear O2s mean nothing and will throw codes till tuned out. I would replace the front O2s asap as you are prolly getting some really shitty gas mileage. As for the others, I am not sure. Did you delete the AIR too?

nik1703

i believe the air is deleted too.

the car has an 01' vette motor. will i need to pickup different o2's? or will 98' camaro o2's work?

nik1703

also, since i have long tubes,



should i be using the rear vette sensor, instead of stock front camaro o2's?

How long did the car sit?

You need 2 new 02 sensors.....you let it sit too long, they are toast. That will happen with us LT guys......

Losing 2 02 sensors at the same time is like losing 2 engines in a twin engine plane at the same time.....1 in a million chance.

Have the rear 02's tuned out.

why does letting it sit for three weeks cause the o2's to go bad?


so do i need rear vette o2's (for the front), or front camaro o2's?
