Both are transmission codes. The 84 is for pressure. It is usually just one part in the transmission. The 81 could a bad part in the transmission or on the engine. Both could be a bad wiring harness it the transmission. Year make and model helps.

2003 kia sorento died. Codes are Po700,Po335, and Po727


be careful on this one. 700 means a transaxle, not sure if its stopped signal or something else. 335 is the crank sensor, i wonder if you have a timing belt that has come or or somethin like that. dont crank the engine until you can get someone to check some things.

Check engine light is on. Codes are p1781, p0113 and p0700. What do they mean? Thanks.


DTC P0113 - Intake Air Temperature Sensor High Voltage
To diag this code you will need a volt/ohm meter. Need to check for 5 volt reference in to sensor from PCM, and ground side of sensor to PCM. Also, check carefully the wires at the sensor. The wires may be broken inside the insulation, right at the connector of the sensor. Pull on each wire slightly and see if it starts stretch. If it does, then the wire is broke inside the insulation, and will need to be repaired.


DTC P0700 - EATX ControllerIs
Is a generic transmission control code. This code lets you know that a specific failure code is stored in the TCM (Transmission Control Module) and needs to be retreived with a diagnostic scanner with TCM reading capabilities. It may or may not be related to the ROM failure in the ECM (Engine Control Module).


DTC P1781 - Engine Torque Signal Circuit
This code is set during engine start up when the ECM and TCM do not communicate properly during initial power up. It will only illuminate the service light if the condition occurs in 2 consecutive start cycles, but the DTC will be stored in the failure records after the first cycle.


Hope this helps.

What does these codes mean P1781, P0731, P1784 AND P0700 AND HOW DO I FIX THEM.


p1781 is manufacturer control transmission, p0731 is gear 1 ratio incorrect, p1784 is manufacturer control transmission, p0700 is trans, control system malfunction. all of these codes refer to tranny.This code normally points to a faulty transmission control module, but this is an expensive part and you should have an experienced Dodge technician diagnose the problem first. or a transmission specialist. the other codes are probably associated with the p0700 code. have a good day !

What does the p0411 p1890 and p1781 mean on a 2001 catera and is it okay to drive til monday til we can get to a mechanic


P0411 is secondary air incorrect flow. THis can be corrected by replacing the air bypass valve, GM # 9192121.

P1890 is the throttle position sensor (input)

P1781 is the engine torque signal circuit.

While driving should be ok I certainly wouldn't embark on a long road trip.

Codes given are p0700 and p1781. Anyone know what these codes stand for? Thanks


The Transmission shop lacks the skills and tools need to do the job. It's best to call around for a shop that has a proper scanner to talk to the TCM computer. The real trouble codes are in there. The best place would be a shop that has a ASE mechanic on duty or the Dealership.

Here what the two codes means:

P0700 Transmission Control System Malfunction
It means you have a trans control problem in the trans computer.
You will need to get it on a trans capable scanner to see what the trans code or problem is.

the P1781 is set during engine start up when the ECM & TCM do not communicate properly during initial power up. It will only illuminate the service light if the condition occurs in 2 consecutive start cycles, but the DTC will be stored in the failure records after the first cycle.
