I have a 1998 Honda accord 2.3 and when I first bought it , it had issues shifting gears and it would rev up then eventually it would drop into gear. I believe its in what's called "Lmip Mode" because it will not rev above 4000 rpms and I changed the oil in it. a city mechanic told me to change the solenoids on the transmission and see if it works. so my aunt buy and sells cars so she decided to by a Obd 2 reader for $400 and I used it this morning and it read code p0706 transmission range solenoid and a bad wheel right front wheel speed sensor , it also reads valve timing malfun
Experienced mechanics share their insights in answering this question :
Hello – this is a challenge, since you have multiple serious problems. The P1259 problem is most likely what is putting your engine into "limp mode". P1259 in a Honda is a problem with the variable valve timing mechanism of your engine. Problems with this will usually cause poor performance, and possible engine damage. However, the transmission shift malfunction issue – which may be yet another problem code not mentioned – can also cause limp-mode behavior. Your P0706 (range sensor switch – detects when you are in Park or Neutral) problem – should not allow you to even start the engine, so not a limp-mode cause. I recommend a Check Engine inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose all of your problems, and give you an accurate assessment of damage and cost estimate for repairs.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
By shutting off the engine, letting it rest for five minutes, and restarting the car, you can bypass or resolve limp mode.
When one of the signals is abnormal, the car will revert to limp mode to prevent further damage. Problems which cause signals like this are usually faulty engine sensors/components/wiring, transmission issues, dysfunctional brakes and clutch, or even low fluid levels.
P0780 indicates a shift solenoid malfunction. If so, you probably wouldn`t need a complete transmission overhaul, just some valve body work to replace the solenoid(s).
Speed sensors, the MAF, MPS and TPS; to name just a few of the essential monitors within your engine. All of these send signals to the control units, so as with faulty wiring, if one of these monitoring units is not functioning correctly, then it could send a message that causes the car to enter limp mode.
The MAF sensor regulates the air-fuel mixture in the engine and might become dirty. The dirt on the sensor sends wrong values to the control unit, and the limp mode is activated.
You can attempt to bypass Limp mode by restarting the vehicle after a short wait or by removing one of the battery terminals to reset the electronic systems.
Limp mode is meant to give your car just enough power to drive home (or to the nearest repair shop) without causing severe damage to the engine or transmission. You can bypass limp mode by restarting your car, topping off fluids, or resetting the battery.
The P0730 code indicates that there`s an incorrect gear ratio in your automatic transmission. The “gear ratio” has to do with the way the torque converter works, and essentially, this indicates that there`s a difference between the rotational speed of the input RPM and the transmission output of the RPM.
What the P0780 code means. The P0780 code means that there has been an abnormality with the transmission shifting. Note that this code only applies to automatic transmissions. This code is also often associated with other, similar codes, such as P0755 Shift Solenoid B Malfunction.
Wipe your dipstick off with a rag, then place it back in your vehicle. Pull the dipstick out again and check the level. If it`s below the marking that signifies if it`s full, it`s time to put more transmission fluid in.
Generally this causes poor performance and limp mode, and customers often complain of a faulty MAP sensor despite the fact it just hasn`t been calibrated correctly, or at all.
in some cases, a failing or faulty tps can cause the engine to go into what`s called limp-home mode. this is a safety feature that recognizes a faulty sensor that could cause damage to the engine or drivetrain. in this situation, you will experience reduced engine power, and you may be stuck in a higher gear.
Clear the check engine light
Use a reliable OBD2 scan tool to clear fault codes and reset limp mode. Just plug into your OBD2 port and search for the correct function.
Can an O2 Sensor even throw the car into limp? If it`s throwing the code for the o2 sensor it won`t go into limp mode, since the ecu recognizes a problem with the sensor it disregards that input.
If the fuel pump isn`t working properly or there is a blockage in the fuel lines, the engine may not be getting enough fuel. This can cause it to run rough and eventually go into limp mode.
Limping (antalgic gait) is usually a sign of a larger issue within the leg or low back. The most common causes include osteoarthritis in one of the leg`s joints, lumbar radiculopathy, or an injury to a ligament or tendon.
When the internal engine or transmission sensors determine a fault exists inside the transmission (which can be triggered by too much hydraulic pressure due to excessive fluid), it tends to create a limp mode, so you can slowly drive the vehicle to a repair facility.
Note: A transmission in fail-safe (or limp mode) will sometimes correct itself when the engine is shut off and restarted. So, if you find yourself in this situation, find a safe place to pull off the road and shut the engine off. Wait one minute and then restart the engine.
Error Code P0730 means the automatic transmission is experiencing a problem, which is usually caused by dirty transmission fluid or problems with shift solenoids.
Symptoms of a Bad or Failing Transmission Position Sensor (Switch) Common signs include the car not starting or moving, transmission going into a different gear than selected, and the vehicle going into limp mode.
You can attempt to bypass Limp mode by restarting the vehicle after a short wait or by removing one of the battery terminals to reset the electronic systems.

The car doesn’t shift into first gear while it works fine in reverse
ANSWER : The problem could be that the internal transmission pump is weak, or the transmission clutch seals are leaking. It sounds like the transmission will need an overhaul.
I recommend having a transmission mechanic test the pressures and diagnose the problems to verify whether you need an overhaul with a new torque convertor.
Clutch engaged with pedal up or down issue? 2006 Mazda 3
ANSWER : Hi there – there are several possibilities here – none of them pleasant, and all will require removal of the transmission to get to the failed bit. It is possible the pilot bearing has seized up – which would make it seem as though the clutch were engaged, regardless of whether the clutch pedal was depressed (and working properly) or not. It’s also possible the clutch pressure plate "fingers" where the throwout bearing applies forced from the clutch pedal and hydraulics are damaged in some fashion, and will not compress to release the clutch disc. Last and least likely is a failure of the clutch master cylinder – internally – since there doesn’t appear to be any fluid loss. I recommend a clutch inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
Engine stalling at low speeds while shifting from first gear to second gear and reverse, with P2757 code
ANSWER : P2757 indicates a torque converter clutch solenoid control circuit issue. If the transmission has been rebuilt, then wiring between the control unit and the transmission may be faulty. The harness connector from the wiring harness to the transmission needs to be checked to be sure the connector is free of contamination. Another possibility could be a faulty torque converter. You may want to enlist the help of a mechanic or service center to assess your stalling issue and determine what is causing the problem.
Automatic transmission issues, high RPM at low speeds
ANSWER : Hello, thanks for writing in about your 2000 Chrysler Cirrus. The transmission control module would need to be scanned to see if the codes stored may indicate the shifting problem you are having. You may have an internal shift solenoid problem causing the shift problem. A speed sensor for the transmission may also cause the transmission not to go past second gear. I recommend having a qualified technician, such as one from YourMechanic, inspect your shifting issue and high RPM problem in person in order to have the correct repairs made.
Won’t shift out of first unless you let go of gas but it will shift back down and never grab second
ANSWER : If you have all the drive shafts in the front and rear, then you will damage the transfer case or one of the axles if you drive the vehicle and engage the front end. The two different gear ratios will do this. As far as the transmission goes, you have a problem with the governor inside the transmission and may have bad second gear parts. Have a mechanic pressure test the transmission and diagnose the shifting issue for you.
Won’t shift past 2nd gear . It drives normal to 2nd gear but wont shift into 3r – 2000 Ford F150 4×4
ANSWER : Hello – I don’t think this is related to switching back to 2WD per se. There is a shift position sensor on the side of the transmission, and it’s possible that the snow activity caused moisture and/or dirt to get into the sensor. I would recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
On interstate, gear shift broke and stuck in first gear
ANSWER : There are many designs for the shifter system in vehicles, and unfortunately there is a known weak point in vehicles similar to your year and model of Porsche. Common concerns often lead to a recall where the part is upgraded or the performance market sees the flaw and make a new part to replace the weak component with. There may be more expensive parts. I recommend getting in touch with the dealer about this to see if the manufacturer can take care of this common problem.
