If you can't find it,obviously your lost or misinformed

What are the probable causes of DTCs P1603, P1604, and P1605?


OBD-II code P1603 indicates an issue with TCU communication.
There are communications that exist between the engine control module, or ECM, and the transaxle control module, or TCM. This communication is done through a control area network, or CAN. With the communication of the CAN, an independent pin and wiring is needed to receive a signal that includes sensor information from the ECM. The more information there is to communicate, the more wiring that is needed. When it comes to CAN communication, all of the information communicated is done alone control modules like the ECM and TCM using CAN lines. When there is a problem with these lines, the ECM will detect the problem and store a P1603 trouble code; the storing of the trouble code is what causes the SES or check engine light to illuminate on the dash.
Possible causes of trouble code P1603 include:
  • Faulty transaxle control module (TCM)
  • Faulty engine control module (ECM)
  • Harness running from the TCM to the ECM has a short
  • There is a poor electrical connection between the TCM and ECM
Diagnosing the exact cause of the problem should always begin with a visual inspection that could reveal bad wiring, loose connections, or damaged parts. From there, it is a matter of running down the list to determine what needs to be replaced. In general, a bad ECM will cause a loss of power, poor fuel economy, and stalling engine. While a bad TCM will have more prevalent transaxle issues like erratic shifting
P1605 and P1605
These codes are indicating a starting problem and rough idling. Code p1604 is a very vague code and diagnosing it without having a symptom is very complicated. And code p1605 is rough idling which means that the computer have noticed a rough idle situation usually this code is accompanied by other codes or if it's alone then I would suspect a fuel pressure issue. These two codes involve diagnosis and we'll need to dig into this problem deeper to find out what's causing them, Unless you are an experienced technician who need assistance then I will suggest that you take your vehicle to your local toyota dealership and they should be able to find the problem.

My 2004 Saturn ion 3 has 2 codes coming up u2105 p0700 an it won't go in drive or reverse what could it be


First off you need to understand your vehicle has several control modules on board . The PCM - engine computer , TCM - transmission control module , SRS - air bag module , Anti theft , antilock brakes , An these modules all are able to talk to each other on a communication network , On your vehicle it happens to be the CAN data bus !
The transmission control module (TCM) uses the controller area network (CAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure that affects emissions has occurred in the transmission control system. When the ECM receives the correct message from the TCM, DTC P0700 will set.
Which transmission does your vehicle have ?
Automatic Transaxle AF23-5
OR
Automatic Transmission VT25-E
DTC U2105-U2199
The controller area network (CAN) serial data line is a high speed serial data bus used to communicate information between the engine control module (ECM), body control module (BCM), and the transmission control module (TCM). Typical data-transmission speeds must be high enough to ensure the required real-time response is maintained. The CAN serial data line does not communicate with the scan tool via the data link connector (DLC). CAN serial data information is interpreted by the BCM and transmitted to the serial data line by the BCM.
I suggest you take this to GM dealer or some other ASE certified repair shop .

What is code p0727


Possible causes
- Faulty Crankshaft Position (CKP) Sensor
- Crankshaft Position (CKP) Sensor harness is open or shorted
- Crankshaft Position (CKP) Sensor circuit poor electrical connection
- Communication error between the Engine Control Module (ECM) and Transmission Control Module (TCM)

The P0727 Codes is triggered when the TCM receives no signal from the ECM.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0727 Description
The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Obd2 p0700


Hi John:
DTC P0700 - Transmission Control System Malfunction
Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults.

If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.

This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem. If this code is present and the MIL (Malfunction Indicator Lamp) is illuminated that basically means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.

Symptoms of a P0700 DTC may include:
Malfunction Indicator Lamp (MIL) illumination
The transmission may exhibit drivability problems like slipping, etc.

More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).

Possible Solutions:
For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.

If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

Hi, you have provided trouble codes p0100 AND p1605.


Trouble Code: P0100


Mass Airflow Sensor Circuit Malfunction
Possible Causes:



Air Intake leaks located after the MAF sensor assembly MAF sensor signal circuit is open, shorted to ground or power MAF sensor has failed PCM has failed


Trouble Code: P1605

A/T Diagnosis Communication Line Malfunction

Possible Causes:


TCM communication line circuit is open or shorted to ground TCM communication line circuit shorted to VREF or power (B+) TCM or PCM has failed TSB 01-004 (01/01) contains information related to this code
For the P0100, check the connector on top of the MAF sesnor for looseness or corrosion. Connector is on top in piocture below. jturcotte_361.jpg

P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

Keep us updated.
