Santa FE SM (2001-06) :: Code P1602 - Limp Mode / No Speedometer
Aug 30, 2016
About a week ago my 2002 santa fe suddenly lacked performance and the check engine light came on . At the same time I noticed the speedometer stopped registering. I later discovered the poor performance was due to the fact that the vehicle was in 3rd gear "limp" mode. The code generated is 1602 "failure to communicate between the ecu and transmission control module". At this point I hoping its just a faulty speed sensor that's causing the problem and not the transmission control module.
Does it indeed sound like a bad speed sensor or does it sound like a faulty TCM or could it be a break in the wires between the ECU and TCM? Also, is it safe to drive the vehicle in limp mode until i replace the part later this week?

I have been having a problem where the Santa Fe will drive great for a week, sometimes only a day and the engine light will come on and the car will go into limp mode. It will drop you from 65MPH to 10 MPH, if you put it in park the RPM's will race and stomping on the pedal will not affect the RPM's. After you turn it off for a couple of minutes it will drive ok again. I have replaced the Throttle Position Sensor and the Accelerator Pedal Sensor, cleaned all connections and checked wires in them. I have also cleaned the Throttle Body. The Dealer wants to replace the Throttle Body.
Had Engine Codes:
P0123 - Throttle Position Sensor 1 Signal Circuit High Imput
P1110 - Throttle Actuator Control System Malfuntion
P0222 - Throttle Position Sensor 2 Signal Circuit Low Imput
P1175 - Electric Throttle Valve Control System (ETS) Valve #
P1196 - Throttle Actuator Control System Limp Home-Stuck

I have a Korean spec 2014 Hyundai Santa Fe 2.2L R-eVGT 6AT 4WD. Around a year ago it started to go into limp mode i had it checked and the error code was p0488 (EGR) Throttle Control Circuit A Range / Performance.
It has gradually become more frequent to the extent it goes into limp mode within a a minute or so . so far the dealer has changed the EGR valve, TCM , the whole turbo assembly and it is no different. They have also stripped and cleaned the intake manifold and egr cooler.

My wife has a 2006 santa fe 3.5l limited over the winter it started acting up went into limp mode and would only go 20mph so I went and picked up a TP sensor well it went out of limp mode so I never changed the sensor well last month it started doing it again so I changed it out didn't work!!! comes up with 2 codes sometimes p2110 and p2118 but normally its p2110 2 times.
If I hit the break it kinda bogs down and pulsates.i took it to my mechanic since I couldn't figure it out and with advice from a hyundai mech. He changed APS didn't fix it so we changed throttle body with used of course didn't work I checked wires and didn't fined any open circuits what are the chances that i got a bad APS or TPS...

I have an issue with my 2004 2.7 Santa Fe. I keep getting fault codes P0335 and P1372, the engine then goes into limp mode and is very hard to start.
So far I have replaced the crankshaft position sensor, the MAF sensor, the spark plugs, new ignition coils and leads.
I have traced the wiring and found no shorts, the only thing which does not match the service manual is that I get 5v on the CKPS sensor wire when the ignition is on, it said it should be 0V.
The car can sometimes run for 50+miles with no issues - then stalls with codes P0335 and P1372. I have a feeling its worse when the aircon is on but cant be 100% certain/

2002 Santa Fe, 2.7 AWD
The transmission has started going into limp mode and causing the check engine light to come on.
The codes given are p0750 and.... I think p0751, for shift solenoids C and D. There is also the generic Transmission Control Module code.
Limp mode only occurs at higher speeds although shifting feels a little rough at times in lower speeds.
If operated in manual mode the vehicle can be driven normally at all speeds without going into limp mode.
Fluid levels are fine.
With limp mode occurring in automatic but not occurring in manual mode, is it more reasonable to believe the solenoids are malfunctioning or the control module itself? I'm inclined to replace the solenoids but find it odd that the vehicle operates normally in manual. Also, can the solenoids be replaced without removing the transmission? It looks like I could get the pan off but am unsure if there is room to get the work done once it is removed.

I have a 2005 2.7L Santa Fe that was shifting poorly and getting stuck in limp mode intermittently. I read up on it and found that it was probably an issue with the input/output speed sensors. The codes confirmed my suspicions and I replaced both the input and output sensors. The codes cleared and the tranny shifted like a dream. Unfortunately after 2 days and 100+ miles the car suddenly started down shifting randomly on my way home from work. The CEL came back on and the car went into limp mode. Could the sensor have gone bad again? Or could it be the wiring harness that plugs into one of the sensors? I don't understand why the car would be fine for a few days and then all of a sudden be acting the same way.

My 2007 Santa Fe was acting up at one time, then stopped doing it, and recently started again. My wife is the primary driver so I'm not always in the vehicle when it happens. When the vehicle is started cold, it will run a short distance then the MIL comes on and it goes to a 5 mph limp mode. After pulling over and shutting the vehicle completely down for a couple of minutes, it will run normally with the MIL still on. However, by the time I get back home to pull the codes, the MIL goes off. I don't remember the exact codes, but when it acted up last time I believe the codes had something to do with the TPS, Pedal Pos Sensor, and one other I can't remember.

Driving on the motorway yesterday, all fine until i lost power..engine light came on, but I was able to continue driving for about 6 miles (trying to get to services) but eventually it would go no further, pulled over and found that the intercooler pipe had come off, replaced it but still no joy.
Recovery van attended and plugged in diagnostic and found a dpf fault and gas pressure valve fault, he cleared the light but i think the faults still remained.. so i had to be recovered home.
The engine will start but it does not quiet sound right, no response from the throttle and if i put it into drive the engine stops.. Its a 2007 2.2

My 2010 Malibu has been throwing a code 0f 2135 also goes into limp mode. Code comes up as throttle pos sen. So looking I can see it is all built in one with the throttle body. Can it be changed with out any special tools?

Got a 2006 GX throwing a P2445 code and car goes into limp mode. Is this the Air Injection Pump? Where it's located?

I've a 2006 sonata 3.3 with 100k miles on it and recently it started going to limp mode leaving me in 3rd gear only after scanning it I've found code p0743 (TCC selonoid open/short circuit) what to check from here or can share any wiring diagrams for this particular circuit I'm not sure where to start. where is the wiring harness for that is located ? is it in the oil pan ? and if I wanted to pull the selonoid itself to check would it be something I can do myself ?

I'm a little bit stuck here. This happened last night, and the dealer is closed today. I have a 2008 Santa Fe SE. It stalled last night, and when I turned it back on, I got a check engine light, the ESC light, and the AWD transmission light blinking. When I go to accelerate, it will not go passed 2000 RPM, and it is driving very sluggish. Its not knocking, or making any other kind of sounds. The air conditioning does not work, but the fan blows uncooled air. It accelerates extremely slowly, even with the petal mashed.
I plan on taking it in tomorrow, but I'd like to know if there is some way to reset the computer. I tried disconnecting the battery for about 30 minutes, but it didn't work.

2008 sonata 3.3, no reverse however the dash indicates it's in reverse. Code P0733. I understand how an unrelated problem can cause another and wonder if I can eliminated possible problems. Car is in limp mode and stays in second or third gear.
I am about to disconnect, clean and wiggle the connectors for the transmission inner and outer sensors and then find out if I can test the sensors. That is, after I find them.
I'm also on the hunt for anything the TPS sensor might have to do with it. Battery disconnect does not work, even after hours. Is there any way something unrelated like the brake light switch or the inhibitor switch (whatever that is), might be the cause? Valve body?

I'm going to do a weld-in-plug delete in my RV in the next couple weeks, and its a crapshoot apparently if it'll throw a code. My immediate concern is I want to go on a trip right after, and I won't have time to fiddle about getting an SCT tuner to turn the code off. What I definitely don't want is a code for EGR flow restriction to eventually cause my motor to go into some kind of limp mode while I'm in the middle of a long drive. Is this possible?

I have a 2001 Elantra GLS 5spd with about 175k. Recently it started driving very sluggish. Under any more than minimal throttle during acceleration or load/resistance (i.e. climbing a hill), it bogs down and will decelerate. No check engine light, no codes, etc. I have replaced the TPS, catalytic converter, Spark plugs and wires, fuel filter, fuel pump, strainer, and fuel pressure regulator. Without any codes, I am at a dead end. I also unplugged the MAP and threw the code for it so I know it is functioning.

I have 1 month left on my AAMCO rebuilt transmission. I took it in a few weeks ago when it went into "limp mode" (Stuck in 1st gear). Eventually, they got an error code of P0730, which I believe is electrical-related. All was pretty good but then today, driving @ high speed on the interstate, I could not get into 4th gear...

I just got an Egde Evo which I installed and everything looked great. After a few runs, I noticed the ABS light coming on an soon after that my transmission goes to limp mode (the wrench lights up).
I receive the DTC error: P2106 on the Edge Evo.
I have gone back to Factory default, but it keeps coming back, ie. the ABS light lights up and the Trans goes to Forced Limited Power (according to the Evo).

Nissan XTerra 2005 transmission RE5R05A. Trouble code is p1757 When I go from park to drive it goes out of gear and puts my car in limp mode. I took it to the dealer and they told me that I have to replace a transmission another place told that it could be brake solenoid or oil filter. In third place they told me it could be the TCM problems.

I recently bought a h&s tuner and installed a dpf delete kit. Everything works great when the truck is not plugged in to the tuner although when I do plug it in, the truck keeps throwing a communications code and goes into a limp mode until I delete the code. I believe it was p0073 but i maye be mistaken. Regardless it has to do with communicating through the obd2 port. I sent the tuner in to get checked out and it turns out its something to do with the truck. I've checked all the fuses and tried to check for broken wires. Where to look next?

F250 7.3L diesel started to flash OD light, goes into limp mode, code p1747. No other codes. Have had issues for a couple of years where the truck would not shift into gear for awhile; sometimes a couple of minutes till it would engage. Have done lots of diagnostics. Visual check harness. Have 12v on pins 1&12 on harness at transmission plug. Plug had some ATF visible, but cleaned it up and continuity good. (with 4" exhaust hard to get to connector).
Checked all solenoid wires with a DVM back to plug at PCM for continuity and shorts, all good. Pulled transmission pack and checked resistance on all solenoids except temp varistor all within specs. Removed Banks Trans Command and rewired tranny plug and pulled Ottomind chip from PCM. Still goes into limp mode and throws code. Did not see any bad solder joints or burns inside PCM by the way.
Seems like PCM right? But here is a complication to my issues. For over a year I have been having electrical issues like the radio not working and windows not working intermittently after starting up. After running for awhile or on restart would work fine. Sounds like the Instrument Cluster issues or relays.(?)
Will be pulling IC and checking for any bad solder joints. However, did not throw p1747 till just recently and now my radio has really gone wonky. It comes on when key is on automatically and then proceeds to cycle through settings; AM-FM-CD.
So questions are, "Is it possible that a bad Instrument Cluster can cause a p1747 code?" "Bad Ground to Tranny" "Can a bad PCM cause a electrical issue in IC??" "Are these 2 separate issues?"
