I might be able to get you a better deal. The code chart is very short for this code, it says, If you have code P0606 go to step A. Toyota Prius Engine Specifications: Engine Type : Single Cylinder Engine Cylinder Type : In-Line Engine Engine Air Intake Process : Supercharged Engine Your Toyota Prius engine control system detects a problem, the computer stores the diagnostic trouble code P0657 in its memory. Note that this is a relatively rare event, and all other repair options must be explored before any control module is replaced. Diagnosing this code therefore requires professional grade equipment, above average knowledge of automotive diagnostics in general, expert knowledge of the application in particular and at least 40 to 50 hours of diagnostic time. If one of the solenoid return circuits does not have the correct voltage returning to the , the will set a code for that solenoid. And you are correct, if there is an immobilizer it is the key that needs to be programmed, but Toyota limits how many keys can be programmed so you probably have to take it to a dealership for them to take care of that.
I had a piggy back system spliced into my harness from when I had a Supercharger on, and I disconnected it and bypassed the wires, and it worked. With this in mind, consult the manual for the application being worked on to locate all grounding points on the vehicle, as well as the actual locations of all control modules. P0657 Description The Powertrain Control Module monitors the transmission solenoid circuits by supplying voltage to the solenoids through this circuit, then checking for voltage returning from the solenoids through each of the individual solenoid control wires. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. The actual number of control modules varies between applications, with some applications having as many as 18, or sometimes more.
Now don't ask yourself; What should you do with P0607 code? If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator. The conclusion is that I was able to fix a potential nightmare problem in a very short time and I learned some valuable information that may help me another day when there is no other help to be found. Given the robust nature of today's emissions control components, it is entirely possible for an individual component to malfunction without leading to an immediate increase in emissions at the tailpipe. Note that some failures will set a code immediately, while others require several fault cycles before setting a code and illuminating a warning light. So far its been very helpfull. Check all ground connections and repair, clean, or retighten connections as required.
Always consult the manual for the application being worked on for detailed information on the exact meaning and correct interpretation of the definition. So while I waited for the replacement I was able to drive the truck by disconnecting the battery every time I started it. Note that if insulation is to be removed from any harness, extreme care must be taken during the process to prevent causing damage to wiring where there was none before. Long story short, i'm working on a friends tacoma that he was changing his battery on and hooked it up backwards. Step 4 If code P0657 or any other code persists after having found no visible damage to wiring, or even if after damage had been repaired and the prescribed drive cycles had been completed, the chances of a successful resolution of the problem are very slim.
To solve P0657 Toyota Prius problem, you'll have to remove the muffler, crankcase and other components blocking the valve chamber. What are the common causes of code P0657? Looks like the piggy back system became faulty. The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool. Some car manufacturers then close the vent solenoid but leave the purge solenoid open. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. P0657 Auto Trouble Code P0657 Auto Trouble Code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission. Ive checked all the connections as well as I can and cant find anything.
The first time I saw this car was from a referral by my local trans shop. Thanks again for the reply and the great thread. P1000 requires very specific conditions to be met before it will clear itself, which conditions can generally only be met by completing one or more drive cycles exactly as specified by the manufacturer. Thus, when a particular control module does not receive an expected signal, or when a particular control module detects a break in communication from one or more of the control modules it should be in contact with, a code is set, and in some cases a warning light will be illuminated. The computer notices the canister is empty when it detects a leaner condition all the vapors are used up and it resumes normal fuel delivery. Repair or replace ground straps as required, clear all codes, and rescan the system to see which codes if any return. I'm sure you payed plenty, and I know in my shop, if a customer's car is not repaired to their satisfaction, I want to know, and make it right.
Proper service data will be necessary. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance. Check and address any fuse problems or obvious wiring faults. I replaced these and double checked the rest to be sure and they are all good. I set my scanner to graph the rear O2's.
Some car manufacturers then close the vent solenoid but leave the purge solenoid open. Step 1 If a professional grade code reader is available, record all codes present, as well as all available freeze frame data. Therefore, attempts to resolve the symptoms will not resolve this code. Yes, i did have the battery disconnected while ohms checking the wiring and the t-body sensors. The computer notices the canister is empty when it detects a leaner condition all the vapors are used up and it resumes normal fuel delivery. The information I found was more than a silver bullet.
An incorrect mixture or injection problems may result in slower performance. How do you troubleshoot code P0657? When I move the wire just right on B2S2 this happens I replaced the sensor and cleared the code. Once the correct vacuum is reached, it closed the purge solenoid and waits to see if the vacuum holds. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. I'm surprised you guys managed to run the truck without doing so.
