Toyota senna 2011 code P 1603,P1604,P1605 car not star


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.

p1603 should help by reading this below

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

Toyota d4d fortuner not starting fault code p1604


For a Toyota, it indicates a startability problem, it is a very vague diagnostic troubleshoot code and therefore not component specific.

Components to check, Crank Shaft Position sensor, Spark Plugs, MAF sensor, fuel pump... etc.

My Toyota fortuner not starting,when we diagnose it shows us p1604 fault code


code p1604 refers to starting system --malfunction===causes--wiring---connections--vacuum leaks--MAF sensor--ignition system--engine coolant temperature sensor--fuel supply system--throttle body--variable valve timing system---A/C system--- power steering control control--- ECM
Try to think back to the symptoms before the engine failed to start
were you in snow, did it get hot, was it lagging in high rpms,
did it just stop or was it misfiring
each symptom will point to an item in the list of causes.

2001 volvo v70 error code p1604 Cannot drive over 25mph. When the code is cleared runs fine for 20-40 miles then reverts to problem. I found a code match for internal throttle signal but not sure what...


if you look that up on a normal OBD code its listed as P1604 Code Word Unregestered However for a volvo thats a code for Control Module Self Test, Speed Monitoring which would indicate the ECM or a wiring problem ( usually just a loose connection,, so check the connections on the ECM, which you can have scanned by the dealer, Volvo codes vary from the normal coding on most cars, so be careful when getting codes and their meanings
