Speed pulse generator code :danbpt

[danbpt]

I have a code for a transmission speed pulse generator or counter shaft how would I repair this I been on google and looking though the threads. I think it's a tcu problem but idk can someone help

Check your wiring to the solenoids. Then try a different TCU. Either grab one from ebay or a junk yard, or find someone local that will let you borrow theirs. If a new ECU gives you the same codes, then the solenoids are bad.

i used the search provided by the web site and found a bunch of stuff on this topic or simlier.
thats where i found this to use as a example .



if you read the "sticky" threads in the technical section, all the info regarding both ECU and TCU codes are well documented.

Could it be that the tranny i have swaped doesn't have sports mode ?. I have a lx tranny my old one from my dx had sports mode. I also already changed the tcu to a lx computer.

what tranny do you have ? what car is it out of?
EDIT......the tcu could be haveing trouble working with the new tranny because they are not men't to work to gethere .

and what year is the tcu?what year is the tranny and the tcu? what model did the tcu come out of? does the s light stay on in d4?

Problem with Honda 1992 Accord
I have a 92 accord. Automatic Trans... Doesnt move.
I have a 92 accord. I was on the highway doing about 65-70 and the car randomly shifted into 3rd gear and the RPM's shot way up. I got it back into fourth the car ran fine. I went to ge tin my car today and put it into D4 and the car doesnt move.. Put it into D3 nothing.... Samething all the way down the line D2 and D1. someitmes if i put it into D1 i can ge *** going but if i hit the gas to much it will just rev up... What could the problem be? the car has bee shifting very hard for about 5 year before this.

It is either your Vehicle Speed Sensor (easy to change) or your Automatic Transmission Computer (capacitors burn out on these boards, there is a fix for this too, the picture is at the bottom of this page). You need to diagnose by removing the lower right plastic kick panel on the passenger side. There you will find a blue plug. With the car OFF stick a paper clip, wire or stuff the plug with foil to make electrical connection so that the two terminals are touching. Then, turn the ignition to ON (not enough to start it though, just power it up). When you do this, count the blinks in the "D Light" or count your blinking Check Engine Light. Both are different but can refer to different things wrong with your car. A long blink is the first number and the short blinks that follow are the second number.
So imagine this as being 14 : ___ _ _ _ _

Below is a decoding chart:

The first section will be the check engine light codes, the next one is the Transmission Control Unit Codes read from the D Light;

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Fuel Tank Pressure Sensor low input
92 Evaporative Emission Control System insufficient purge flow

TCU Codes:

CODE LIST:

1-Lock-up solenoid 'A' circuit open or shorted.
2-Lock-up solenoid 'B' circuit open or shorted.
3-Throttle Position Sensor circuit open or shorted.
4-Vehicle Speed Sensor open or shorted - No signal from speedometer.
5-Shift Lever Position Switch circuit shorted.
6-Shift Lever Position Switch circuit open.
7-Shift Solenoid 'A' circuit open or shorted.
8-Shift Solenoid 'B' circuit open or shorted.
9-Counter shaft or transmission speed pulse generator open or shorted.
10-Coolant Temperature Sensor open or shorted.
11-Engine RPM (Ignition coil signal) open or shorted.
12-(No code 12 used)
13-Main shaft speed pulse generator open or shorted.
14-Linear (line pressure control) solenoid open or shorted.
15-Kick down switch circuit shorted.

this is the speed sensore for the tranny [IMG][/IMG]

you could be having problems with these.

this is the vehicle speed sensore.

The tranny speed sensor is already with the tranny that I have I think ima just have to put the old speed sensor back . I did have to cut and splice a sensor on the side of the tranny wonder if that could be it . I already read that info but thank you again for helping out guys .

[danbpt]

and what year is the tcu?what year is the tranny and the tcu? what model did the tcu come out of? does the s light stay on in d4?

All out of a 1992 lx out of the code I gave above earlier ,

ya that can be butt also does the year of the tcu and the year of the tranny match . the hafto be the same year.

Thats not true, I have a 92 ex tcu in my 91 lx. The 92/93's tcu programming is a comprimise between the sport and regular/overdrive modes found on 90/91's. The sport button doesn't work anymore with the 92/93 tcu, and while in d4, the sport light will stay on all the time, but if you shift down to d3, or any other gear I think for that matter, the sport light will turn off.

And to the OP, you should really check the condition of the connections point where you "spliced" a new connector for a different speed sensor. Or try the old sensor, since you said you still have it.

yes if you shift down to d3 then the s light will turn off but you will be at higher rpms. is what im trying to say thats not always the case remimber mine when it went out . i used my friends spare till mine was done . his was out of a 93 ex and kept giveing me weird problems and throughing codes .
