2000 chevy blazer crank no start. I was told it overheated and has been parked ever since. (one year). I replaced cap, rotor, plugs and wires. wont start and only one code P0122. please help


I'm not sure about a Prius? If cranking rpms sound faster than normal, you need to check compression.
You may need fresh fuel? After it sat that long I may have pulled the plugs and tried the crankshaft by hand, plus add few drops of oil in each cylinder, before cranking.
I saw what you replaced, what testing have you done? Did you visually check for spark at the plugs, engine cranking. Key on engine off, did you use a gage and check proper fuel pressure, with the spider fuel system, 60--66 psi. After it is started it may run with about 10 psi less. Engine cranking you have fuel injector pulse?
The code is for throttle position sensor. Three wire connector, 5 volt ref--ground--signal. You can use digital multimeter to check signal wire, just turn on the key, move throttle by hand, watch the voltage, closed throttle .36--.96 voltage, wot 4.0 min. Voltage should move up and down smoothly.

Tip

Replacing Throttle Position Sensor on 2004 kia sorento


My issue was my Engine light came on and I went to Autozone and O'reilly's to have them scan why my engine light came on and they told me it was putting up Error Code P0122. Looking at some forums and post was able to fix my issue on my own. Now if you replace your TPS module and the issue has not cleared you can move on to the next step in troubleshooting your error code, but in my instance the replacement fix'd mine. Here is the process I used which took about 10-15min and saved me about $300;

1. Obtain new part (I ordered my OEM part from ebay $30-$60)
2. Disconnect battery,Positive side.
3. mark the current position with a sharpie or something, you want to install in the exact position the original one was in before removing. (take a pic with your phone).
4. Disconnect the wire to the TPS module/unit.
5. Unscrew the unit (should be x2 screws, note how tight the screw is, you'll need to put same tightness when re-applying screws).
6. Put new Module/Unit in place matching the original position of the old one, just line up where you made the marks and secure with screws.
7. re-connect the wire back to the TPS module/unit.
8. re-connect battery.
9. start your car and your done.

Your check engine light should be off now for code P0122. if still on, it may be another code and if so continue troubleshooting the other codes/issues. This process resolved my Error Code P0122.

2003 ford expedition check engine light is on. It is reading a p405 code which is the egr sensor. I have change the sensor and the pig or electrical code twice . I brought the sensor from ford.


This DTC says nothing about changing the sensor or the connector or pig tail ! It's a circuit voltage low code
P0405 - DPF EGR Sensor Circuit Low Voltage Detected See DTC P1400 Problem with wiring or PCM !
P1400 - DPF EGR Sensor Circuit Low Voltage Detected The EGR monitor checks the DPF EGR sensor signal to the PCM for low voltage. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value.
  • DPFEGR circuit short to GND
  • Damaged DPF EGR sensor
  • VREF short to GND
  • Damaged PCM
A DPF EGR PID reading less than 0.2 volt with the key ON and engine OFF or running, indicates a hard fault.

Po 122 problem light on had changed sensor problem not fixed trans not shifting right horrible jurks when it shifts.


P0122 is TPS signal low, which could mean you have a bad TPS, or a fault in the wiring or connector. I suspect a bad Throttle Position Sensor.

Hi i have a 97 chevy with 312,558 mileson it been having problems so i finally put it on the computer and found 8 codes they are p0102 p0118 p0122 p0170 p0174 p0300 p0420 p0430 now thing i have...


What model of chevy? What is engine litre size? What are the problems? I\'d give it an overall tune-up. Erase the codes and see if anything comes back. Just a note, by erasing the codes, you may loose any freeze data that you other-wise may have. Did you use a gage and check fuel pressure. Not only check for correct fuel pressure, if no internal pressure bleed-off, check that the pressure will hold for a bit with everything off. Any more, 02 sensors are part of a tune-up. Can you check if system is running rich or lean?



Do you want me to list the code definitions or can you look it up? Removing the cat is illegal, if you live in a state that doesn\'t do sniffer tests or vehicle inspections, you may get away with that.

P0122 and po700


HI. Lets start with the P0122 Code.

This code is in reference to the TPS(Throttle Position Sensor). A P0122 code essentially means that the the vehicles computer has detected that the TPS is reporting a low voltage condition. On some vehicles, the lower limit is 0.17 - 0.20 volts, respectively. This can occur if the TPS was not recently installed correctly or mis adjusted. If you have not installed it recently, than the most likely actions are to replace it, asap. Here are the most common symptoms listed below:

1. Rough idle
2. stalling during acceleration or stumbling at a red/stop light.
3. poor acceleration

If you are not experiencing those symptoms, it will most likely be intermittent and clearing the code may resolve the problem for a short time. If this should be the case, i would check the wires for rubbing against the housing or grounding faults. Again, make sure it is adjusted properly if recently installed.


The next code will be the P0700.

This is a serious transmission control unit code. You will need to take this vehicle to the dealership for the correct scan tool. You will need to extract the special codes to actual repair, correctly. Usually, the entire module will need to be replaced. A regular scanner will not pick up the TCU codes. This is a dealership code. Most Kia's are covered with a 10 year/100,000 warranty, so this should be covered.
