IS F (2008-2014) :: CEL Code P0137 - VSC Light Keeps Popping Up Every 30 To 40 Miles
Oct 6, 2014
So I bought LOLM3's old Borla a while back & everything's been great except CEL P0137 & the VSC light keeps popping up on me every 30-40 miles. I have a 12' with 20k miles on the odo.
P0137: O2 SENSOR CIRCUIT LOW VOLTAGE (BANK 1 SENSOR 2)
It has secondary cats welded on along with these type of O2 defoulers so the O2 sensors can reach the re-located bungs (except they're welded, not screwed on):
I've swapped sensor 1's with bank 2's sensor & even went ahead & replaced it with a brand new one, same code keeps popping up . Resetting the light is getting old & inspection time is coming up!
There are no audible exhaust leaks as far as I can tell, would a minor leak throw the CEL?Should I cut out the secondary cats & replace with straight piping like how the exhaust was originally made?

Got my oil change done 2,000 miles ago and already have the oil maintenance light come on after 2,000 miles. I still have over 3,000 miles before I am due for an oil change. And also have noticed a drop in fuel economy of 4-5 mpg. What's going on?

Had my Check Engine light come on so I went by a local AutoZone to see if they could read the code. He said it was P0137, but what his reader can't tell is which one it is.
A co-worker pointed out where it was on my 2006 2.4, but I'm not sure if it's the sensor in the engine bay or the one closest to the catalytic converter. The engine bay looks easy to change out but I'm in no condition to be crawling around underneath.
Which sensor the P0137 is referring to?

I need to know the Fire order for the 2011 toyota camry se 2.5 L engine. so I can find which oxygen sensor I need to change. I m getting a P0137 code and it said is the bank 1 sensor 2. I think that is the one after the catalytic converter but need to find out for sure.

Getting backfire or popping noise after deceleration with our cars. It didn't do it before with oem exhaust, just wondering if we're going to get a little bit from my new joe z exhaust, or do I have a leak somewhere with my installation. Or do I just need it break in a little more. How do I check for leaks , Do I just need to ramp the car and check all the flanges for where the exhausts bolts up and check for alignment issues.

So I just wanted to ask 2 things.. Am I the only person who purposely shifts at certain rpms from 1st-2nd just to hear the burble/popping out of the exhaust.. I hold it around 3k and the shift and let off the gas and it's a Orchestra of amazing noises that are Oh so addicting. Secondly, are there any negatives to doing this... Or that sometimes I hear the loud thud/pop when slowing down but not every time... What is the true cause of these glorious noises.

Just bought a used 2012 IS-F 1-owner with 37k miles. Clean Carfax and AutoCheck - very, very clean car.
Test drove it with my wife, fell instantly in love, and signed the paperwork. As part of the dealer delivery, they gave a full tank of gas and washed/waxed the car.
While enjoying the 8 mile drive home in 5:00 traffic, regular speeds of 40-50 mph without any start/stop on the freeway and surface roads, I noticed that the range (distance to empty) on the full tank was only 169 miles!
I realize this is a hi performance V8 - but c'mon! Is there something wrong with the car?

My ECS light comes on after driving about 15 miles. I checked computer to see what code it was sending. It was a 73. I looked up the code. It is the ignition pulse system. What is this and how can I fix it.

Set up the free oil change for next week (10,600 on the odometer) and was wondering if this is an automatic light just based on mileage. Prior owner got a free 5,000 mile oil change and selling dealer changed the oil at 5,800 when we bought it.
But I guess if there's a reset somewhere that neither prior dealer took the time to do the car thinks it's time for it's first change. This is a 2014.5 SE Sport put in service July of 2014.

So today during my drive I looked down and noticed my check engine light come on! The car has 7k miles on it!! All I've done to it was the ARK cat back and k and n drop in filter. I'm guessing O2 sensor but it's crazy to think a car with 7k miles had a bad sensor. Noticed the car was running a little rough lately but noting too crazy.

So this morning when I started my car for work, the engine warning light turned on.....Last night it was perfectly fine. What surprised me was the car is only 3500 miles in. Why encountered the engine light issue this early in their ownership of the IS?

I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

I have a 2008 Sonata Diesel version, and I am getting the engine management light on. All the times i have scanned it, it says - Insufficient air flow to EGR Valve. This gets automatically reset in a day. Now the weird thing - This is happening only if I drive in and around Heathrow airport I have done 100s of miles elsewhere and this problem never occurs. But if I just drive 20 miles to Heathrow, my engine management light always comes on which resets in a day.
I am really confused on what is happening here.

I've got a check engine light on but the truck runs fine. I checked the fluid levels everything seemed normal. Any special trick that I could try to reset this check engine light myself? It's got the 4.6 L, Stock no mods, been keeping the regular service intervals at the dealership.

My ABS light resets itself when I leave the truck, but when I go down the road later, after a few miles it lights up until I turn the engine off again. It's a 2008 Lariat Super Crew 60 K miles. I've searched and seen only a few posts related to the ABS. One item I've seen mentioned is a sensor on the rear differential. What other parts are in the ABS system that may cause a light to come on. How to troubleshoot the system would be great, too.

just recently installed the new X force exhaust system on my 2008 ISF with 72,000 miles on it. I've had the exhaust on the car for about 300 miles it when I was driving home from work today the vsc and check engine light pops up. I turn the car off when I got home and then turned it back on the check engine light was off but the stored Code was still there when I read it with the scanner P0420. I'm thinking maybe there's an exhaust leak even though it sounds fine.

2007 GS450h Lexus owner, and have got a few error codes appearing on her They are as follows:
Quote:
P0031 - Powertrain
HO2S Heater Control Circuit Low (Bank 1 Sensor 1)
P2195 - Powertrain
O2 Sensor Signal Stuck Lean bank1 Sensor1
P2238 - Powertrain
2) O2 Sensor Positive Current Control Circuit
Low bank1 Sensor1
P0138 - Powertrain
O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
Am I right in saying, these are all just a dodgy bank 1 sensor 1 (engine bay) and possible sensor 2? Is replacing them myself feasible?

Why in the would I keep getting a VSC light on.

I'm having issues when shifting into reverse and I it goes into limp mode when the wrench light shows up. This will not happen when shifting into Drive. When in limp mode I get engine code P0720. This calls for a bad Output Speed Sensor and my research says the sensor is on the back of the transmission but I cannot find any sensors on the transmission. there are several connectors clipped to it but I don't see any bolted in sensors. Also I cannot find a replacement sensor anywhere so I'm wondering if this is a generic code.

Starting here to ask first but I currently have the CEL and VSC light both lit and 1st gear is locked out. What is causing this without having the codes read yet? Is it common to get both of these lights simultaneously? Having 1st gear locked out seems very concerning from a mechanical aspect to me, should I have it parked till I get it serviced?
