Having an Acura vehicle with P0336 code points to a defective crank sensor. This code will show up everytime the crank sensor sends a defective speed signal to the engine computer (ecm). The symptoms for this P0336 code are long cranks and hard starts accompanied by the mill light in the dash. The engine could also show signs of misfiring and surging. If this code appears, reset the code first and see if the code re-appears. If it does, check the crank sensor wires, sensor resistance and replace the crank sensor if necessary if found out of range.

When testing Acura crank sensor wires, concentrate on the connections located at the front pulley which might be rubbing a metal causing the short. Follow this connection until you are convinced the wires are safely routed and insulated. If in doubt, you can peel the wiring harness to get a closer look. If after correcting this and replacing the sensor and the code still is coming back, trace the wiring connections of the sensor up to the ecm pins. Check the wires for continuity, corrosion in the plug-ins and tightness. Otherwise, check for mechanical cause such as a jumped tooth in the front timing gear which can require a timing belt replacement. Sometimes, after the timing belt is replaced, this P0336 code comes up which shows that the crank sensor wires were pinched during the timing belt replacement.

TIPS:

This code repair above assumes you have done basic repairs such as replacing the spark plugs, clean EGR system including throttle body with brake spray cleaner, etc.

Sometimes, after replacing the crank sensor, you might change the cam sensor too. Contact ATS for more details.

Thanks!
