I have a 03 GLI 24v VR6 thats throwing a P0113 code, which is for the intake air temperature sensor. The sensor is part of the MAF sensor, ive tried 2 brand new BOSCH MAF sensors yet the same check engine continues to reoccur. Is there anything else that oculd be triggering it to come on? Is there anyway to bypass/disable it through vagcom?
View 8 RepliesMy 2003 Mk 4 Golf have had a lot of error codes and I have cleared most (O2 sensors, thermostat, and Mass Air Sensor) I now have an error P0113 which is the Intake Air temp Sensor.
So I need to clean the sensor first then maybe replace it, but I can't find the sensor on the intake manifold.
I have looked all through the U-Tube info, but nothing matches my 2003 Golf 2.0L ....
Now I've had this constant problem with this code that I just cannot get rid of. I've read many threads on here but nothing seems to be working. I currently am on the third maf that I've been able to test out, still throws the code. Connector is all clean, nothing wrong there. It is clean every time I just can't figure it out.

I own a 2003 VW Jetta GLS 2.0L 4 Cylinder and my CEL recently came on throwing the PO420 code (Catalyst System Efficiency Below Threshold (Bank 1)). So I replaced both the upstream and downstream O2 sensors. Well just one day after replacing the sensors the CEL came back on with the same code. I was wondering weather or not I should replace the whole catalytic converter or if there was anything else I should try. The car runs fine, exactly how it did when I bought it.
View 22 RepliesI'm working on a 2003 Jetta GLI 1.8t (MT and 140,000m if it matters). The CEL has been on for a couple of weeks because of an exhaust leak throwing a catalyst efficiency code. After I make this post I'm going to run down to the advance auto I used to work at & see if I can borrow the scanner to see if there's anything new, but as of right now I don't know. I'll update the thread if I find anything.
The car started yesterday AM perfectly fine. Started again when I left work around noon. No problems with the start, idle, acceleration.. it's all good.
3 hours later I tried to start it to go pick up my kid from school but it just cranked without firing and would not start. I took care of business with the kiddo and then started trying to pin down the problem.
1. Opened the door & listened for the fuel pump to prime.. No sound.
2. Noticed the dome light is on.
3. Checked ALL of the fuses on the side of the dash.. All are fine. Turned key to listen for secondary prime.. no sound.
4. Bought Fuel pump relay & replaced.. no change.
5. Cursed.. a lot
6. Bought fuel pump.. replaced.. no change.
7. Cursed a lot more.. and cried a little too.
8. Noticed the fuel pump was now priming with the key being turned, but still not when I open the door.. Dash indicates the known CEL, but now I notice that the EPC light is on too (this could be from all the fruitless cranking drawing down the battery charge)
9. Figured I'd throw in a new crank angle sensor cuz of the EPC.. no change.
10. Shot starting fluid down the intake.. didn't hit a lick.
I feel like I'm at a dead end.. It's acting like a bad ignition control module, but there's no such thing on a vw 1.8t.
I keep throwing a P0411 - Secondary Air Injection System error. My previous pump was seized so I replaced it, and broke a few of the chintzy air hoses in the process. Now, with new pump installed and new air hoses connected, I can go about 5 days before the code comes back on.
So to recap, I have:
Replaced the air pump
Verified the new air pump functions, yepReplaced the air hoses
Verified connection of air hoses at all junctions
Checked the Secondary Air Relay for function
I have not yet checked the solenoid - unsure how to do so.
So the check engine sign came up on my car and using the OBD it tells me the error is P0113. After googling the information, it looks like I have an issue with IAT sensor.
I opened the air filter and what I believe what could be the sensor and there was nothing clogging up, so I'm assuming the sensor needs to be replaced
Question is where is the IAT sensor located and how do I dis-assemble it so I can replace it. Is it the piece that is located just before the air filter?
So my mom recently bought a 2003 Elantra (75K miles, auto trans) and within a few days the CEL came on. She took it in to PepBoys and had them hook it to their scanner to get the codes out of it. The only code that came up was P0113 Intake Air Temp (IAT) Sensor high input. I've done a little research on the net but there is a lot of random info for this code out there. Is the IAT a separate sensor or is it combined in with the Mass Air Flow (MAF) sensor(if this car even has a MAF) or combined in with the MAP sensor? I've read on the net that it could be any of these 3, I think it's combined into the MAP.
I've also read that this code could be caused by a bad IAT, bad O2 sensor, an exhaust leak, bad wiring/ground(I checked the wiring/grounds visually and everything seems ok) or many other things. If it's as simple as replacing one of the sensors I can do that myself, I just don't want to go randomly buying things and either it be the wrong part or have it be the right part but not fix the problem. The car runs great, even with the CEL on. Yesterday when she stopped by my house I disconnected the battery for a couple minutes and reconnected it, started the car & no CEL. She drove the car for about 125-150 miles before the light came back on.
I have a 2003 Elantra GLS. I am intermittently Check Engine light and error code is P0113 - Air Intake sensor issue. I can't locate where the sensor is. I don't see any wire coming of the tubing that connects the air filter to the engine.
View 18 RepliesI recently had an issue with a coolant leak. the Y shaped coolant line connection went bad located under the power steering reservoir. The car got hot and the coolant light came on i immediately turned the car off and saw coolant leaking out from this.
Now today I start my car it has a rough idle and dies once it dies it doesn't start again and the epic light comes on throwing the codes

Throwing 2 codes -
P0172: too rich
P1176: post cat 02 reached limit
Last time it turned on it had horrible air flow, it felt as though it was choking. definitely not a misfire. occasionally after spirited driving the engine would die after I came to a complete stop then worsened to cutting off when I put the clutch in at high rpms. also have a slight loss of power. I also recently added a 3" tbe and changed coil packs.
So my car has been dropping multiple codes after I scanned her and found all five: p0303, p1128, p0172, p1300, p0301. She is just a simple five speed AEG and has no mods other than a SRI. I already replaced the MAF but that ended up causing more codes and I have checked the vacuum lines to no avail.
View 2 RepliesI am stage 1 tuned and just have simple bolt ons. About a year and a half ago i had my CEL come on and it was P2400. I was still under warranty and took it into the dealer. They ran through the whole eval system along with replace my evap pump and the CEL was still on. Well then they replaced the ECU and all was fixed. that following fall i took it to APR to get ref lashed and all was well. Until 2 weeks ago. The CEL is back on throwing the same code. I believe its the ECU again and I'm waiting to get into APR to have them fix whatever it is. They believe its evap but I'm not convinced.
View 2 RepliesSo recently I took my engine apart to do a valve cover gasket and Ecs tuning 2.0 coil conversion. I noticed a good amount of oil in the plug tubes so I got out my trusty soap dispenser and started pumping out oil. Pulled plugs and cleaned them (wanted to make sure oil was all out b4 getting new) also while I had it apart I wanted to take intake off, ( just to polish it and clean out any carbon inside).. Well I never ended up doing that. I removed the injector connections and realized it was to much work for such little satisfaction. So I plugged the injectors back in.
I got my car all back together and now I'm throwing 6 cel codes!! P0102 (maf) which I'm assuming b.c I took it off for so long, p0201, p0202 ( injector 1 and 2 miss), then some misfire codes p0300 (random) p0301 (cylinder 1) and p0304 (cylinder 4). The car starts runs very rough then cel comes on and blinks. I was thinking maybe the oil getting down to the combustion chamber couldn't be the best for it but it would just burn off. Only other thing I did was take off the thottle body and cleaned it.
Last weekend I installed a usp test pipe with a hfc welded in and now I am throwing the code p0160......
What this is and maybe some ways that I can fix it?? I have a hard time believing an o2 sensor is shot since the car only has ~27k miles....
97 F150 4.6 200xxx on recent rebuild. My truck is throwing P0171 & P0174.
I think I tracked it down to leaky IAC and EGR gasket. I sprayed both with carb cleaner and the RPM's dropped.
My question is, wouldn't the RPM's rise instead of drop? I was under the impression that they would go up if the gaskets were leaking. Or did I use the wrong spray?
What I need to do to fix these codes
p0171 system too lean bank 1
p2637 torque management
p0420 ...
The car doesn't seem to run that rough.
Replaced coil pack and spark plug wires with parts from O'reilly auto
16684 - Random/multiple cylinder misfire detected
P0300 - 35 -10 - Intermittent
16686 - Cylinder 2
P0302 - 35 - 10 - misfire detected - intermittent
16687 - Cylinder 3
P0303 - 35 - 10 - misfire detected - intermittent
I have searched and browsed multiple websites and threads to no avail. They all seem to be dead ends.
So my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.
View 2 RepliesA couple months ago I was hearing a hissing noise under the hood throwing the same code replaced the Valve cover, after there was no issues. Yesterday saw I had CEL and I was throwing P0174 code and there is a similar vacuum leak sound coming from under the hood but the Breather in the valve cover is not sucking in air. The Oil cap comes off but the engine starts to bog, what it could be now?
