Wil your oxy sensor trigger check engine lite

this code is lazy cat (or weak or dead)420's are very hard to diagnose
here is the order.
1: NO EXHAUST leaks near any oxy sensor. zero, (cracks, or gaskets) any where near or upstream of any oxy sensor.!!!
2: Engine runs perfectly CEL out running and no stored or live DTCS (besides 421) and engine holds closed loop at hot idle and light flat cruise, steady right foot, if not , the CAT gets punished.
3: good front oxz sensors, a mUST.
4: AND 2nd last , new rear cat sensors (421s come from this sensor)
5: a NEW cat.

that is the crash course, can do 100s pages.
but no. just 1.

you really need to drive it for min of 30 minutes before you go, they need time to heat up and run a cycle,

The knock sensor is on the back side of the engine bolted onto the block. It looks like this

Two things; 1) check the coolant level of the coolant overflow. Sometimes when the coolant level is low it will trigger the check engine light to come on. 2) If the car is running hot or high check the thermostat. These are the least expensive ways to go, before any costly repairs.

P0410

Definition
Secondary Air Injection System fault
Explanation
The air injection system is monitored for faults
Probable Causes
1) Circuit relay defective or fuse open
2) Check connector and wiring
3) AIR pump defective or hoses blocked


P0128
Fault Code Definition

• Engine temperature has not increased and/or reached the correct level within a specified amount of time after engine startup
  

Common Problems That Trigger the P0128 Code

• Defective Engine Thermostat
• Defective Engine Coolant Temperature Sensor
• Defective Intake Air Temperature Sensor
• Defective Cooling System
• Low Engine Coolant
• Dirty Engine Coolant, causing incorrect Coolant Temperature Sensor readings
• Defective, always running Engine Cooling fan(s)

As for the po128 I would replace the thermostat first. That is the problem 99% of the time.

Good Luck

get car scaned first for codes

O2 Sensor Circuit Slow Response Bank 1 Sensor 1
this is the sensor that is located in the exhaust just off the engine and before the cat converter, so it is the front sensor.

check you ignition components to see if they are worn or faulty, this is usually the cheapest part that can cause this problem since your tach runs off the ignition.check fuel filter before fuel pump as this could be clogged and also not as expensive as a pump or oxy sensor. a faulty oxy sensor will set a code.

P0135--OXY SENSOR HEATER CIRCUIT(bank 1 sensor 1)

Here are the code definitions.hope it helps.
