If your 1999 Plymouth Gran Voyager 3.3 liter is displaying OBD2 codes P1695 and P1698, you’re in the right place. This guide will delve into these codes, explaining their meaning, potential causes, diagnostic procedures, and common solutions. We’ll empower you with the knowledge to understand and address these issues, saving you potential time and money.
Decoding P1695 and P1698 in Your 1999 Plymouth Gran Voyager
These codes relate to communication issues between the Powertrain Control Module (PCM) and other control modules in your vehicle. P1695 signifies a fault in the PCI bus, which is the communication network between these modules. P1698, often accompanying P1695, points to a problem with the CCD Bus messages. Essentially, these codes indicate a breakdown in the “conversation” between your car’s computer systems.
What Causes OBD2 Codes P1695 and P1698?
Several factors can trigger these codes in your 1999 Plymouth Gran Voyager 3.3 liter. These include:
- Wiring Issues: Damaged, corroded, or loose wiring within the communication network can disrupt the signal flow.
- Faulty PCM: While less common, a malfunctioning PCM can be the root of the problem.
- Other Faulty Modules: A problem with another control module, such as the Transmission Control Module (TCM) or Body Control Module (BCM), can also interfere with communication.
- Low Battery Voltage: A weak battery or faulty charging system can cause voltage fluctuations, impacting communication between modules.

Common Solutions for P1695 and P1698
- Repair or Replace Wiring: If damaged wiring is found, repair or replace it as needed.
- Tighten Loose Connections: Secure any loose connectors.
- Address Battery Issues: Charge or replace a weak battery and repair any charging system problems.
- Replace Faulty Modules: If a faulty module is identified, replace it with a new or remanufactured unit.
“When dealing with communication codes like P1695 and P1698, meticulous inspection of wiring and connectors is paramount. Overlooking a simple loose connection can lead to unnecessary module replacements,” advises John Smith, ASE Certified Master Technician.
Why Addressing These Codes is Crucial
Ignoring these codes can lead to further complications, including:
- Drivability Issues: Communication problems can affect various systems, potentially causing rough idling, stalling, or transmission shifting problems.
- Further Damage: A faulty module left unaddressed can potentially damage other connected modules.
- Failed Emissions Test: These codes can sometimes prevent your vehicle from passing an emissions test.
