SOURCE: Car runs greAt BUT FLASHES LITE PO300 P1781

P0300 is a random engine misfire code. P 1781 is a transmission code, but it refers to a malfunctioning engine speed signal (crankshaft angle sensor). A bad crankshaft angle sensor or camshaft angle sensor can cause the P0300 code. A large list of items can cause a P0300 code, but since you have both, I'd be checking the crankshaft angle sensor and the related circuit. Sometimes, the mounting screws loosen up, which can cause the sensor to not function properly, all the time. Get this fixed, because over a period of 4 to 6 months, this can destroy the catalytic converter in the exhaust system ($$$$)

SOURCE: po452 trouble code changed sensor engine light

you may have to drive it several days for the light to go off, or have the codes cleared. personally I would just drive it. if the computer tests it, and it passes the test, it will go off on its own.

SOURCE: 04 Silverado no second gear

check color and smell of trans fluid, if not bright red and had a pugnant odor then the trans needs to come out and torn down, You can try a fuel filter that can cause a driveability problem

SOURCE: 2000 chevy silverado not running good, stalling

This is the code for the fuel pressure sensor, either the pump is failing or the sensor is bad causing the computer to screw up the air gas mixture. Also this code is for fuel tank pressure sensor it could be bad wire or sensor or pcm computer need scanner to do the test may be local shop can help or dealer

SOURCE: the transmission, 4L80E, will not shift out of first, abs light is on, no speedometer, no heat or a/c, all at the same time, then all went back to normal with gerky trans shifting, then all went to ma

it could be the same problem as you have before.
it was two years, it must have regular check up or cleaning on this parts. the proper maintainance keeps engine in good condition meet problem only sometimes..

Hi....
if your car get a VSS code the Transmission control module.
Will command the Trans, in LIMP MODE.
Is mean you only will have 2 gear.
If you replaced the VSS sensor allready.
Maybe you have A electrical problem.
The First step is Check the condition of the VSS connector.
Remove the Connector and pull the wires a little each by each one.
To see if is broken inside of the Plastic cover.
IF you can
GIVE ME the Code number I will help you better.
Because is there more that One speed sensor on your trans..
Check the grounds on the Intake manifold, Black wire one of the wires is for the speed sensor.
The RED/YELLOW wire coming from the INSTRUMENT CLUSTER,
Is mean you need to check the Fuses that work with the instrument cluster. FUSE # 12 10amp, And # 30 10amp.
Located at fuse block left side of dash.
Is there a ground that work with the Cluster and Combination Meter. Behind left side of dash Black wire.
Check the Connection of the Cluster.

OK.. I hope this help on your problem.
Thank you for use fixya.

Need help locating vss on trans for a 2000 F350 4X4 7.3 motor


1. Your ABS/ VSS can be removed and cleaned with just a clean rag, no need for wd-40 or any other solvent, also carefully clean out the hole on top of the differential, lift the vehicle (place in neutral) and check the sprocket wheel inside the pumpkin for possible missing teeth or to see if it is loose.

2. The VSS (part # F85F-9E731-AA) can also be tested with an ohms meter, it should measure ~1.9 K-ohm or higher (lower than 1.9 requires replacement).

3. The VSS is a hall-effect sensor, connect a volt meter to the sensor connector and wave a piece of metal (pair of pliers or flat metal) about a half inch away from the sensor, and you will consistently see a variation in voltage, if no movement on the volt meter is observed, replace the sensor.

4. You also have the two front wheel ABS sensors, try cleaning them first, and carefully reinstalling them.

5. When the VSS sensor is malfunctioning, the PCM may try to get input from the TSS (turbine speed sensor, top of the transmission), and as it turns out, the same return wire is used by the OSS (output speed sensor, tail end of transmission), check these two sensors also, clean them and test them (1.10 K-ohm or higher). These are also Hall Effect sensors, so check for voltage as described in paragraph 3 above.

6. Pay attention to see if your ABS light blinks when you start the vehicle, just before it stays solid. If this is happening, count the number of blinks, as this is actually a code and the blinking means the vehicle is trying to communicate with you.

7. Last, if nothing above corrected the problem, I would start tracing RFI (radio frequency interference), one sure area is usually your fuel pump (wires running along side VSS wiring. ABS/VSS wiring is routed directly to the ABS module.

I hope this information works for you.


There are two "speed sensors" though that can be confused at the parts store. They don't look the same but they are listed almost the same. The one on the rear diff is listed as the "ABS speed sensor"....the one on the tranny is listed as the "Speed sensor" The rear one is the cheapest and easiest to replace...about $12.

Transmision will not shift the codes are co327 and co236


Faulty rear wheel speed sensor.You can reset the computer with a code reader or a scan tool then test drive it.If problem comes back then replace the rear wheel speed sensor.You will have to test them to figure out which one is faulty.

I have a 2003 gmc envoy 4wd I have codes co237, co236 my abs light is on what does this mean


Codes indicate rear wheel speed sensor fault, this part of ABS system. A mechanic will need to inspect sensors.

you might try unhooking the battiey for 20min both + and - posties cuz that will force the computor to have to resest only if you have addressied the fuel pressure problem which taht would most likly be your filter which isn't all that much

My 1996 S-10 Blazer will not shift sometimes and the ABS light comes on. This problem goes away after I drive it for awhile. The code I get is P0502 (vehicle speed sensor low imput). Would a bad speed...


A faulty VSS (Vehicle Speed Sensor) or related wiring can cause both of your problems, trans and ABS. If the computer doesn't know the vehicle is moving, then it won't shift the trans. If the ABS controller sees wheel speed, but not vehicle speed, it will turn on the ABS light. The VSS is located in the rear transfer case housing. But remember, it may be the VSS, related wiring, a faulty speedo buffer (usually located in the dashboard), ECM, or even the reluctor on the transfer case output shaft. You may want to have a shop scan "data stream", or even have them diagnose the problem.

My chevrolet express 2500 has a problem . the ABS/TCS


This could be a little hard for the average person to fix. C0055 is the reason the ABS lite is on and it has to do with the speed sensor circuit. PO502 is also related as it has to do with the VSS circuit and will require some specialized equipment to correctly diagnose and repair, Sorry.
PO753, Locate the fuse block on the IP. Now locate the "IGNITION 0" fuse and replace it because it is blown.This will correct the P0753 code and correct the transmission shift inhibit problem.

Speed sensor on 2000 ford f150 4x4 triton 4.6


if this helps, please rate as fixya. thanks.

Vehicle Speed Sensor The vehicle speed sensor (VSS) (Figure 43) is a variable reluctance or Hall-effect sensor that generates a waveform with a frequency that is proportional to the speed of the vehicle. If the vehicle is moving at a relatively low velocity, the sensor produces a signal with a low frequency. As the vehicle velocity increases, the sensor generates a signal with a higher frequency. The PCM uses the frequency signal generated by the VSS (and other inputs) to control such parameters as fuel injection, ignition control, transmission/transaxle shift scheduling and torque converter clutch scheduling.

For the 4R70W trans vehicles

Vehicle Speed Sensor (VSS)

The vehicle speed sensor (VSS) is model dependent. Possible sources of vehicle speed input are, anti-lock brake sensor (ABS), a gear-driven vehicle speed sensor (VSS), or the transmission output shaft speed (OSS) sensor. On 4x4 applications with a manual shift transfer case, the transfer case speed sensor is the source of vehicle speed. The VSS signal is either an AC signal whose frequency changes with vehicle speed, or an SCP data message depending on the source. Some vehicles have both. The vehicle speed signal is an input to various vehicle sub-systems such as the powertrain control module (PCM), instrument cluster (speedometer and odometer), speed control systems, etc. The vehicle speed source must be operational to enter output state control mode for diagnostics.

If you have a 4R100 trans, it is different.
