P0833 OBD Error Code: Problem & Solutions

<<See All OBD Codes

This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it will depend upon the vehicle make and model. Also this problem is in association with the vehicles having manual transmission only.

On manual transmission vehicles, the powertrain control module (PCM) monitors clutch and gear position to manage engine performance and fuel economy. Also, clutch and gear position are needed for engine starting, cruise control operation, and possibly a remote engine starter. Regarding clutch position, there may be one or two clutch pedal position (CPP) sensors, depending on vehicle design.

While the clutch pedal has a range of motion, between fully-disengaged and fully-engaged, the PCM generally needs to see the clutch at either of those two positions. When the PCM determines the clutch is fully engaged, it enables engine starting and modulates engine speed, such as for rev-matching upshifts and downshifts. When the cruise control system detects the clutch is fully released, it enables cruise control function. The PCM can monitor CPP sensor function by analyzing other parameters, such as gear position, throttle position, engine speed, or vehicle speed.

If the PCM detects a problem, such as not detecting the clutch pedal fully-released, even though other engine parameters indicate that it is released, the PCM sets diagnostic trouble code P0833, “Clutch Pedal Position (CPP) Switch “B” Circuit,” and illuminates the malfunction indicator lamp (MIL).

What causes this problem with the Clutch Pedal Switch B Circuit?

• Affected CPS (Clutch Position Sensor)
• Bad CPS switch circuit
• Poor electrical connection to the sensor
• CPP sensor harness corroded, shorted or open
• Corrosion/damages to electrical connectors
• PCM may be faulty

1. Powertrain Control Module - The PCM can also be at fault and can lead to P0833 getting stored and flashed in the system. Buy new module now!
2. Diagnostic Tools - Use professional OBD scan tools to diagnose an OBD code error problem. Buy quality diagnostic tools from us now!
3. Clutch Position Sensor Switch - CPS switch, if faulty, will not be able to send the output voltage to the starter to start the engine. Thus, replace faulty CPS switch now!
4. Clutch Connector - Clutch connector needs to be checked for damaged and corrosions and thus, must be replaced immediately. Buy new clutch connector now!

If you are facing OBD error code P0833, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Faulty Clutch Pedal Switch
• Engine not starting
• Clutch Pedal Switch harness is open or shorted
• Clutch Pedal Switch circuit poor electrical connection

We have listed out some ways which would help you to correct the occurrence of OBD Code P0833. They are mentioned here as follows:

• Defective clutch position sensor replacement
• Misadjusted sensor has to be readjusted
• Damaged, shorted, or corroded electrical elements must be repaired or replaced
• Replacing or reprogramming the PCM

However, if you face any issue then we have stocked a wide range of best priced Clutch Position Sensor Switch, Fuses, Clutch Position Sensor Connector, Fusion, Clutch Pedal Position Switch Harness, Powertrain Control Module more to help you out in fixing your car.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0833 code to be stored:

A scan tool will be helpful in diagnosing this problem, but a DVOM (digital volt-ohm meter) will give you the most stable results, the reason being that the scan tool can only show you what the PCM is seeing, not what the clutch pedal position switch is actually doing.

The CPP sensor is typically a contact switch, that is, only returns an “On” or “Off” signal to the PCM, so you can use your DVOM set to resistance or continuity, to test CPP Sensor “B.” A current repair manual and electrical wiring diagram will give you the exact location and circuit diagrams to properly diagnose this problem.

All circuit checks should start by making sure that all connectors are properly seated and that there are no bent or back-out pins, nor evidence of water intrusion or corrosion. Repair as necessary.

Check your repair manual to make sure it reads open or closed in each position, that is, some CPP sensors may close the circuit with the clutch pedal released, while others might open the circuit with the clutch released, and vice-versa.

If resistance does not change with the pedal depressed or released, there might be a switch problem or an alignment problem. If the switch is adjustable, it may need to be positioned closer to the pedal. Otherwise it may need to be replaced.

If the switch is internally shorted or open, it will need to be replaced. If you measure proper resistance across the switch in each position, you may have a circuit problem. Reconnect the CPP sensor and disconnect the appropriate PCM connector. Repeat the resistance check from the PCM connector.

If resistance does not change with the clutch pedal depressed or released, you most likely have a problem in the wiring harness. Aftermarket remote starters may also interfere with this signal. Disconnect the CPP and recheck. If you have a short circuit or any kind of resistance, it will interfere with the CPP signal. Repair as necessary.

If resistance changes as expected, it’s quite possible that the PCM is reporting a false circuit problem, usually due to driver error. “Riding the clutch” is the most-common problem, since the PCM has determined that the clutch is “released,” but the driver is keeping the pedal just off the switch. This often happens in stop-and-go traffic, such as in a construction zone or rush hour. The PCM doesn’t see the signal, so it sets the DTC.

Common mistakes while diagnosing P0833 code

Repairing the electrical components, or the faulty PCM itself, without checking for further issues is the most common mistake made when diagnosing OBD code P0833. Usually the fault in the PCS will not be registered until another issue requires the PCS to register some communication to PCM. This means that there is another repair possibly needed, and by only addressing the immediate cause of the P0833 code, there could be a necessary repair going ignored. Also, examine all the faulty error code in the order in which they are stored in the system.

• Wiring and connector issues
• PCM and TCM error
• PCS harness and TCM harness faults
