Please advice and show any information about UP, DOWN stream of O2 sensor replcaement on cl600 (2001)
Wish to change the set(4) but does not know which is Down nor Up stream and its Location.
Also the correct OEM# or where to buy it.
thank you very much for your concern

HI PMERCURY
Thank you for all the info you posted. you are the man, with this kind of info i think i can dismantle the whole car not to mention the silly O2 sensor. Much appreciated for your helps.
Did you know that everywhere i took the CL600 to fix or some advice they think I'm or the car is a desease or sickness or something so you know how happy i'm to get helps from you.
once again thank you very much. I know where i'm going to get helps from now .

 

Hi PMERCURY, I dont know how to send picture to your inbox so i posted here so you would understand my question.
thank you very much

• Bank 1 Sensor 1 is the upstream (pre-cat) on the passenger side.
• Bank 1 Sensor 2 is the downstream (post cat) on the passenger side.
• Bank 2 Sensor 1 is on the upstream (pre-cat) on the driver side.
• Bank 2 Sensor 2 is the downstream (post cat) on the driver side.

always replace by pairs, like tires ! left and right
so both upstreams or both downstreams, or all 4

 

Check engine light codes associated with a bad oxygen sensor.

Bank 1 Sensor 1 (Upstream) (pre-cat)

• P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
• P0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1)

• P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
• P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
• P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
• P2080 Exhaust Gas Temperature Sensor Circuit Range/Performance (Bank 1 Sensor 1)
• P2081 Exhaust Gas Temperature Sensor Circuit Intermittent (Bank 1 Sensor 1)

Bank 1 Sensor 2 (Downstream) (post cat)

• P2031 Exhaust Gas Temperature Sensor Circuit (Bank 1 Sensor 2)
• P2032 Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 2)
• P2033 Exhaust Gas Temperature Sensor Circuit High (Bank 1 Sensor 2)
• P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
• P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
• P0138 O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
• P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2)
• P0140 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
• P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Bank 2 Sensor 1 (Upstream)

• P0150 O2 Sensor Circuit Malfunction (Bank 2 Sensor 1)
• P0151 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 1)
• P0152 O2 Sensor Circuit High Voltage (Bank 2 Sensor 1)
• P0153 O2 Sensor Circuit Slow Response (Bank 2 Sensor 1)
• P0154 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
• P0155 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)

Bank 2 Sensor 2 (Downstream)

• P0157 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 2)
• P0158 O2 Sensor Circuit High Voltage (Bank 2 Sensor 2)
• P0159 O2 Sensor Circuit Slow Response (Bank 2 Sensor 2)
• P0160 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
• P0161 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)

 

Hi PMERCURY
Thank you very much for your posted and answer in the PM. Yes, I got it all now, I will wait for the parts(O2 sensor) arrive and go with it. and YES I'm sure is cylinder 7-12 for sure I had to check the scanner much time and always came the same code PO300, P0307-P03012. Hopefully after install the new Voltage transformer that problem will be gone.
by the way when you said Voltage Transformer! is this the one (see picture). I will look into purchase one. At the moment I think I know where it is( you see it after taking the air filter out is the black box right in the middle I think I will double-check this.
once again thank you very much and I will post the result soon.

my pleasure

I still need broken voltage converters for my project here:

anyone having any please pm
any V12 voltage converter is ok, they are all the same apart the cover

 

Hi PMERCURY
I'm looking to buy one with a good price but it seems impossible, it is so expensive, it ranges from 500US to 1200US( double it in AUD$) bloody hell.
for me to fix it is IMPOSSIBLE, so I'm still looking for a decent price on refurbishing one or something, As soon as I change it for sure I will contact you send it to you the broken one.
I'm not sure I can locate one in Australia or not for the time being, but if you have some contact or info to purchase with a fair price one please inform me I would much appreciate.
For the time being, the car run ok ( not to it real potential) but is a second car so I would have time to chase one around for a fair price.
I will keep you posted
thank again
william
