What causes the Transmission Control System code p0700?
P0700 is set when the PCM detects a malfunction in the transmission control system. This malfunction causes the vehicle to set a Check Engine Light and trigger a failsafe mode. Once the failsafe mode is set it will remain until the fault is repaired or normal operation is detected. What causes the P0700 code?
What does the OBD code p0700 stand for?
P0700 code definition. P0700 is a generic OBD-II code that is indicating a fault within the transmission control system.
Why is the Check Engine Light set to p0700?
P0700 is set when the PCM detects a malfunction in the transmission control system. This malfunction causes the vehicle to set a Check Engine Light and trigger a failsafe mode.
What does the p0700 DTC stand for?
P0700 is a diagnostic trouble code (DTC) for “Transmission Control System Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.00.
What does the p0700 GMC code mean on a car?
P0700 Gmc Description. The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light.
What to do if your p0700 is having trouble?
Monitor the Slip Speed, Lockup Duty Cycle and Output Shaft Speed for irregularities. One thing to try when fixing the P0700 code is to clear the code and take it on a road test. Before clearing out the data, record all present codes and any data from the scan tests. After the second road test, look for the codes that appear.
What is the OBD-II scanner error code p0700?
P0700: Transmission Control System Malfunction. The OBD-II scanner error code P0700 problem is a generic code that applies to vehicles equipped with OBD-II. It refers to the transmission control module (TCM) in the automatic transmission. The P0700 code is informational. The code points to a general fault, not a direct fault.
How much does it cost to repair a GMC p0700?
The cost to diagnose the P0700 GMC code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
What does P0420 mean on Honda Civic EX?
After months of normal driving with no problems, my 2003 Honda Civic EX check engine light came on during a long trip. Got it scanned and it’s P0420: Catalyst efficiency below threshold bank 1. They said it could be a bad catalytic converter or oxygen sensor. I borrowed a scanner and tried to measure the oxygen sensor readings over time.
What is P0420 catalyst efficiency below threshold Bank 1?
Got it scanned and it’s P0420: Catalyst efficiency below threshold bank 1. They said it could be a bad catalytic converter or oxygen sensor. I borrowed a scanner and tried to measure the oxygen sensor readings over time. Doesn’t seem to have good time resolution:
Where does the P0420 trouble code come from?
P0420 is triggered in the engine control module when there is a problem with the efficiency of the catalytic converter. The engine control unit uses two O2 sensors, one in the front of and one behind the catalytic converter to measure the efficiency of the catalytic converter.
What does the p042x code stand for?
All P042X codes (where “X” can be any number) refer to the catalytic converter and exhaust system. P0420 refers to the catalytic converter or – more specifically – the oxygen (O2) sensors before and after it on the bank 1 side of the exhaust system.
What causes a P0420 to read a steady lean condition?
An exhaust system leak really screws up the P0420 testing routing. An exhaust leak near the upstream sensor can cause the downstream sensor to read a steady lean condition. The ECM would interpret that as a bad catalytic converter.
What does it mean if your OBD code is p04020?
It is important that the front and rear o2 sensors pass the Mode 6 tests. If they fail, false readings could potentially confuse the OBD-II software and trigger a false P04020 code. In most cases, the failing catalytic converter is not dangerous and poses no risk to the occupants of the car.
Where is the fault code stored in a p0700?
P0700 means that a fault code is stored in the TCM. However this doesn’t rule out the possibility of a failed PCM or TCM (unlikely). For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module.
When does the TCM detect a fault, it sets a p0700?
If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory. This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem.
What causes a p0700 code on a transmission?
There are three main causes of a TCM failure, which result in a P0700 code. – Low or dirty transmission fluid. Your transmission needs clean, full fluid to run properly. Low or dirty fluid can cause your transmission to overheat and results in excess friction between moving parts. – Faulty wiring.

What does the p0700 code on the ECM mean?
The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission controls. Need more information on how to fix the P0700 code? Need more help?

What is the diagnostic code for transmission control system?
P0700 is a diagnostic trouble code (DTC) for “Transmission Control System Malfunction”.
What happens when the transmission control system malfunctions?
When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module ( ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission controls.
