Just like you, we see our share of new and unique vehicle problems. The 5 Fast Fixes below are examples of some recent head scratchers that we worked through with customers on our Repair Hotline.

These short-cut tests and confirmed fixes are now at your fingertips along with more than 700,000 Hotline Archives in Direct-Hit.

Vehicle: 2004 Honda Accord EX 3.0L, V6, MFI, SOHC, Eng Desg J30A4
Mileage: 165,000

Customer Concern: P0970. Problem in the A/T clutch pressure control solenoid valve C circuit. The trouble code set after the transmission was replaced.

Tests: 1. Check the internal continuity of the clutch pressure control solenoid valve C, specification is 3-10Ω. Compare to clutch pressure control solenoid valves A and B. Solenoids A and B are on top of the transmission, they are a linear pack with color coded brown and black connectors. Solenoid C is on the front of the transmission by the starter.

2. Check pin 2 of clutch pressure control solenoid valve C, Black wire, for a good ground. This should have 0.05 V drop or less. Add a ground as needed. Check G151 on the transmission.

3. Check for a duty-cycled power to clutch pressure control solenoid valve C on pin 1 Green/Red wire when commanded. You should be able to command this with a scan tool. Check the wiring between clutch pressure control solenoid valve C and PCM pin C22, check wire for open or short, load test wire.

4. Power clutch pressure control solenoid valve C manually, check the amperage draw of clutch pressure control solenoid valve C, compare to A and B. Replace as needed.

  • Potential Causes: A/T Clutch Pressure Control Solenoid Valve C
  • Clutch Pressure Control Solenoid Valve C Wiring
  • Clutch Pressure Control Solenoid Valve C Ground
  • Powertrain Control Module (PCM)

Confirmed Fix: Replaced A/T Clutch Pressure Control Solenoid Valve C

Tech Tips: This is an electrical circuit code that sets when the PCM sees 0.2 amps or less with a commanded duty cycle of 57-89% or when the PCM sees 0.4 amps or less when the command is 89% or more.
