wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! now you are spamming,BECAUSE HE DOESN'T WANT TO DO IT,HE WANTS YOU TO BUY A TRANNY TOO!

if you are using the same m otor then you can

P0115 Engine Coolant Temperature Circuit Malfunction

did you clear the code with the scanner and the same code came back? P0115 Engine Coolant Temperature Circuit Malfunction

To me this sounds more like a IAC (Idle Air Control Valve) or your MAF (Mass Air Flow Sensor) is bad and not reading correctly. The fuel pump sensor is an actual relay that you saw, its goes into the fuses. Not really sure what someone told you that it was, due to the fact that you do not have a sensor. Do you have any check engine lights on?

Do you have black smoke or what looks like soot coming out of the tail pipe. The check engine light monitors fuel pressure through the computer and pressure regulator. It will come on if the pump pressure is too high or too low. If the pressure regulator is faulty it could cause excessive fuel consumption,

Sounds like you may have a bad intake manifold gasket, or if its oil, bad tube seals

It sounds like it's been flooded with fuel. Take the plugs out and dry them off then put them back in. When you start the car, hold the accelerator/gas pedal down (don't pump it). This will help to remove any excess fuel from the cylinders. When started, let go of the accelerator (obviously :) )

i presume its an auto box, if so the input and out put sensors are under the air box, i would remove the battery + tray as well,then the air box. you will need a 10mm spanner for the battery terminals and all so 10mm socket for the sensors them selves, every thing else will come off with a 12mm long reach socket + an extension bar, the sensors them selves are on top of the gear box which is on the left hand side of the engine. you also have to loosen the bolts holding the transmission cable to get to one of the sensors,

The start circuit on most cars disengages the accessories circuit when trying to start the car. This is because of the large current draw for the starter motor. If however this is new then have a load test done on the battery as a dead cell also cause this problem.

Bank 1 is located towards the driver's side. Sensor 1 is located upstream just below the exhaust manifold. EOBD II Error Code: P0134 Description: Oxygen Sensor (O2S) 1, Bank 1/Heated Oxygen Sensor (HO2S) 1, Bank 1 - No Activity Detected Possible Causes: - Wiring. - Signal wire between the Heated Oxygen sensor and ECM is disconnected. - Heated Oxygen Sensor defective. - ECM.

The company has a good solution and they will fix it for you when taken to the service center. Check for Recalls, you no doubt have free repairs waiting to be done.

That doesn't mean anything, most Asian cars need the battery connected to run . It is how the alternator is wired.

Trouble Code: P01167

HO2S-11 Controller Adaptive Test (Bank 2)

HI, this code represents a fault within one or both of the O2 sensors that are located on the exhaust system i will list the possible causes of this code you are receiving.


Possible Causes:

Air leaks after the MAF sensor, or in the EGR or PCV system

Base engine "mechanical" fault affecting one or more cylinders

Exhaust leaks located in front of the A/FS or HO2S location

Fuel control sensor is out of calibration (i.e., ECT, IAT or MAP)

Fuel delivery system supplying too little fuel during cruise or idle periods (e.g., faulty fuel pump or dirty, restricted fuel filter)

Fuel injector (one or more) dirty or pressure regulator has failed

HO2S is contaminated, deteriorated or it has failed

Vehicle driven low on fuel or until it ran out of fuel

Sounds like you have connected to the wrong wire. Best to take to an auto electrian i would think.
