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

Codes 1238 1618 1132


I would assume that these are 'P' codes.Please advise if they have a different letter prefix or nothing at all.
P1238-This Relates to Turbocharger (TC) boost pressure sensor - boost control malfunction
P1618-This Relates to Cable fault between AW 50-Q2 TCM and Motronic 4.4 ECM (lamp lights)
P1132-This Relates to Heated oxygen sensor (H02S) 1, bank 1/heated oxygen sensor (H02S) 2, bank 1 - signal incompatibility
Try deleting them all first then just focus on the ones that wont reset,followed by those that come back on after driving or using that area.
Hope this helps you.

Looking to find out what Volvo error code 1633 means


Code 1633 is not a manufactures code, it is a genetic one, and is not as specific as a volvo code.
The best thing to do is take it to a volvo shop and get the specific code.
I did find a meaning for it------- speed signal missing or absent.
That could mean either a wheel speed sensor, or a vehicle speed sensor is at fault, that's why you have to get the specific code.

DTC code-P1618 = fault in lead between aw 50-52 and motronic 4.3. what does this mean and were is it on the car . its a vovlo s 40 year 2000, made 09/99 motor is 1.9 gas auto trans


aw50-52 is the transmission. motronic is the fuel system. it means the two modules are not communicating with each other.you will need a pinout diagram for these modules and go from there.its difficult to remove computers on late volvos without the speciall tool.furthermore getting an acurate diagram other than a volvo service manuel [paper service manuels were discontinued in 2000].will be near impossible. in this case it makes sense to bring to the dealer.

There are 4 codes I need to know about P0810, P1132, P1618, and P1633, 2001 Volvo V-70 24T


810 neutral check, incorrect connection
  • Check the transmission and control module connectors. Check for contact resistance and oxidation according to Checking wiring and terminals. Permanent faults
  • 1132 front o2 sensor signal too high
    1618 dtc is in another module
    Volvo does not provide information regarding DTC P1633 for many of their models.
    However, it has been reported that various Volvo engine control modules will produce this code. The code is associated with a missing or inaccurate vehicle speed signal from the ABS control module and may be accompanied by DTC P0722 or P1618.

    Possible causes:
    - Defective vehicle speed signal to the ABS control module
    - CAN connection problem
    - Defective ABS control module
    - Defective engine control module

    Manufacture codes associated with this P code may include ECM-510f, 530d.
